You’re definitely not alone in this ordeal, given that hundreds of other players—if not thousands—have been barred from playing online in the wake of this hassle. Find out how to get rid of this persistent issue by following the methods outlined in the guide ahead. Let’s jump right into this solution-rich guide without any further ado. 

Key Highlights
  • This error can occur when you try to launch COD Warzone but get stuck in the lobby after getting past the title screen, with the screen freezing and a pop-up message showing up, which says“DEV ERROR 6039 [common_mp.fc].
  • There are several things that can cause Dev Error 6039, these include a corrupted game update, invalid or missing game files, or a problem in your platform.
  • You should first try the simplest and fastest fix, which is restarting your system completely, as this fix is quick and easy enough to do while having decent chances of fixing Dev Error.
  • If you are using either a PlayStation 4 or 5 console, then you should try to change COD Warzone’s storage location, as the location where your game is stored could be the reason behind Dev Error.
  • If you have an outdated system, then it is likely the culprit behind Dev Erroe. You should quickly check if there are any updates yet to be downloaded, and if so, you should download them and then see if the error still persists.
  • You can also try to rebuild your PlayStation 4’s database and see if that fixes Dev Error 6039, as doing so can help replace any corrupted files and clean up your system completely.
  • A small number of players have managed to fix Dev Error by simply lowering the graphic settings of COD Warzone, as too much load on your system that it might not be able to handle can also lead to this error.

  • After trying all of these solutions, dev error still persists, then you should try the final fix, which is reinstalling COD Warzone entirely, as this is one of the most effective ways of fixing the error.

What Does Dev Error 6039 Mean in Warzone?

At that time, a prompt surfaces and states, “DEV ERROR 6039 [common_mp.fc].” The problem can occur anywhere, even if you manage to get inside a match-up. Some players experienced this scenario and had their copy of the game crashing 15 seconds into the start of the round, so it can be difficult to diagnose what possibilities are giving rise to this bug in Warzone.

The following is our round-up of the most robust methods there are to fix the issue in question. Be sure to follow the outlined guidelines meticulously for the best results, now that you know where the Warzone dev error can possibly stem from.

Restart the System

We’re going to start off with something exceptionally simple here. If you haven’t done this already, then make sure you try restarting your console or Windows PC to potentially resolve the dev error in question. What this does is refresh the game for you, so the system loads it better the next time it’s turned on. There’s no need to progress to advanced methods of error-fixing strategies if the dev error can be resolved by a mere restart. 

If you’re on a PC, click on the Windows Start button in the top-left corner and then select the “Power” button. Once you do that, multiple options will appear in the designated area for you, making it easy to click on “Restart.” As soon as you’re finished there, the PC will shut down and then proceed to turn back on. Try launching Warzone now to determine if the problem has been fixed. 

If you still cannot play the game, then it appears the issue we have is more deep-rooted for fixing it than what a mere restart is capable of. That said, there are plenty of more stratagems to employ, so keep on reading and don’t lose hope just yet. 

Change the Storage Location 

This fix is recommended to perform on the PlayStation 4 and the PlayStation 5 consoles. For whatever reason, it’s actually the storage location on these consoles that is giving birth to this persistent problem. This is especially true if you’ve got an extended storage or an external drive connected to the system for extra space. We’ll simply be changing the storage location of Call of Duty: Warzone in this promising fix.

Some players were able to get the game working after approaching this measure, so here’s hoping that you can say the same. The following instructions will guide you on how to do this successfully for the PlayStation 4 console. They should be fairly similar if you’re on the PlayStation 5.

1. The first step is to head over to the “Settings” section of the console. The app icon is shaped like a toolkit and can be accessed from the upper row of apps on the PS4 home screen.

2. You now have to scroll down and find “Storage” in the console’s settings. Click on “Storage” when you find it to continue.

3. Now, the next step is all about picking the right storage to find your copy of Call of Duty: Warzone inside. You’ll be faced with two options: System Storage which is the console’s ingrained storage space and Extended Storage which is what you have connected to your PS4 externally for extra space. If Warzone is sitting in System Storage, click on it to get to the next step. If it’s not there, return to the previous screen and select Extended Storage.

4. After locating Warzone in, say, System Storage, press the “Options” button on the DualShock 4 and select “Move to Extended Storage.” You’ll get the opposite if you find Warzone installed in your Extended Storage compartment.

That’s about it! This is one of the definite fixes to the Warzone dev error 6039 ps4, according to a number of people who replicated the process on their end. Try it on your end and see if it resolves the issue for you. You should be able to play Warzone just like before, but if the situation still isn’t mitigated, keep on reading for more potential solutions. 

Update Your Console and Warzone

The next fix in line pertains to updating your PlayStation 4, PlayStation 5, Xbox One, or Xbox Series X|S consoles. Individuals on the PlayStation 4 seem to have benefited the most from downloading the latest updates for their system. It appears that some part of the console is disrupting Warzone from running properly, thereby making the dev error arise and wreak confusion in its wake. 

That is why you need to pay heed to the System Software Update section in the “Settings” area of the console. Double-check if there’s an impending update that your console can download and install. People have had their Warzone issue fixed from successfully getting their PlayStation 4 on the latest update release, so here’s hoping you can do this too. 

In addition to updating your console, and this truly goes without saying, never ignore an update for a live-service game such as Call of Duty: Warzone. Half of the issues are taken out just like that when you keep your titles up-to-speed, similar to how the developers want you to play the title. Therefore, it doesn’t matter if you’re on PC or on console, check Warzone if it needs to be updated. If it does, don’t waste a single moment in going forth with it.  

Rebuild Database on the PS4 

If you cannot play the title on the PlayStation 4 due to this pertinent dev error, there’s something you can try to hopefully resolve the issue. The console at hand sports a high-quality feature in its Safe Mode called “Rebuild Database.” This functionality helps users fix a ton of issues with the PlayStation 4, including the clean-up of corrupted game files, and even helps boost up the console in terms of overall performance.

There’s a lot of good that can come from using this feature and it doesn’t matter how often you use it. Players have reported that the Warzone dev error 6039 issue first resulted after the game got upgraded with the Pacific update. This was obviously a while back from today, but the flow of updates for Warzone is constant, and you never know when you’ll get hit with this problem again. 

Our point is that rebuilding your PS4’s database specifically tends to this part of downloading huge game updates. Oftentimes, our console gets convoluted with an awful lot of downloaded data, no matter if it comes from installing games or downloading their relevant updates. At the end of the day, in this case, the console has to work hard to dig out the data it actually needs from the database when running a particular process.

Rebuilding your database cleans unwanted junk and restructures the database of the console so the system can find it easier to run games and perform better. To learn how to do this, follow the steps listed ahead for the best results. 

1. The first step is to turn off your PlayStation 4 console. If it’s currently in “Sleep mode,” wake it up from its slumber, and press and hold the “PS” button on the DualShock 4. This should reveal the “Quick Menu” sidebar and allow you to head to the “Power” section. Select “Turn Off PS4” and wait for the console to shut down completely. 

2. You now have to connect your DualShock 4 controller to the PlayStation 4 console with a USB cable. Our aim now is to boot the system into Safe Mode so we can rebuild the database, but that cannot be done unless you use a wired connection. 

3. After you’ve plugged in the controller with a USB cable, press and hold the “Power” button at the console’s front until the PS4 makes a beeping sound two times. Once the final beep is heard, let go of the button. 

4. You should be shortly seeing “Safe Mode” on the screen now. If you don’t, however, it probably means that you released the “Power” button too early. Repeat the process until you boot the PS4 into Safe Mode. Once done, select the fifth option, which should be “Rebuild Database.”

That’s about it for the most part! All you have to do now is wait until the operation concludes. You will be prompted to restart halfway through the process, so simply follow the on-screen instructions and you’ll be good to go. The PlayStation logo will soon appear afterward and take you back to the home screen from where you can access the console’s working interface. 

Try launching Warzone now and see if the issue was resolved. There’s a good chance that the dev error 6039 is now going to perish, but if the hassle still doesn’t cease to exist, keep on reading to try other things to do. 

Lower the Graphics Settings 

A niche group of players in the Warzone community forums claim that lowering your graphics settings in Warzone helps resolve the dev error 6039and keeps other related issues down to a minimum. Moreover, it bears noticing your PC’s hardware requirements can factor in quite heavily here. If you’re playing on a device that barely reaches the minimum threshold required to run Warzone, you should definitely consider lowering the graphics. 

To do this, click on the “Options” button while in the lobby of Call of Duty: Warzone. Hover over to the “Graphics” tab next and disable Dynamic Resolution and V-Sync. Next, click on the “Quality” area as highlighted in yellow in the screenshot below and lower or disable the following settings. 

  • Streaming Quality
  • Texture Resolution
  • Texture Filter Anisotropic
  • Particle Quality
  • Bullet Impacts and Sprays
  • Tessellation
  • Dismemberment and Gore Effects
  • On-demand Texture Streaming

Once done, quit the game and make sure you terminate it wholly from the Task Manager as well. Start the game again, launch into the lobby, and try finding a game to see if the Call of Duty Warzone dev error 6039 has been resolved. If you still haven’t managed to get the game working, we still got a couple of promising solutions left to attempt.

Turn Off Your Antivirus Software, Especially Avast

Turning off the antivirus software, both Windows Defender and any third-party program that you might have installed on your PC is the definitive fix for the Warzone dev error 6039 bother. In addition to this, a whole swath of users in the overall community claims that Avast Antivirus is the main culprit behind this error code. Upon disabling the application entirely, the game started working again and the issue disappeared in thin air. 

Therefore, we encourage uninstalling any third-party antivirus that you might have installed on your Windows PC. Don’t be afraid of impending security threats since we’ll only be doing this for a brief while in order to confirm the antivirus program’s link to the dev error. Search for “Remove apps and programs” in the Windows Search bar and you’ll get taken straight to the area from where you can uninstall your Windows software. 

Select the antivirus that you have installed on the system and remove it from the device. Once done, restart your PC to shut down Warzone if it’s running and refresh the computer. Launch Warzone as soon as the PC boots back up to see if the bug still exists. 

Other than that, if you do not have any other anti-malware software installed, you’ll need to turn off Windows Defender then, which is the operating system’s default antivirus system. For this purpose, the following steps are going to guide you from start to finish.

1. Get started by searching for “Windows Security” in the Windows Search bar. Click on the application when it pops up to get to the next step.

2. Right after that, select the “Virus and threat protection” section to move forward. In the final step, you should be able to disable your Windows antivirus software.

3. In the final step, simply turn off the following features in the “Virus and threat protection settings” section. All you have to do is click on the respective toggle underneath each setting to disable it. This should be fairly simple to complete.

You’ve successfully gone through the operation. The protective shields of Windows Defender Firewall are temporarily off, prompting you to check if Warzone works on your end now. Try launching the game now to see if it’s finally working. If not even the removal of your antivirus software does the trick, then it appears there’s one last thing you can do.  

Reinstall Call of Duty: Warzone – Definitive Fix for Console Players 

If all else fails and you’re basically left without any hope, go ahead and uninstall Call of Duty: Warzone from your console or PC. As far as we’ve had our research extend, a reinstallation is the most definitive way of fixing the Warzone dev error 6039issue. The strategy at hand works for Lego Star Wars: The Skywalker Saga Bugs along with the Paladins Invalid Game Executable Error.

Plenty of players were able to sit out the installation times and get back into the multiplayer action of Warzone shortly after reinstalling it completely. If you’re on PC playing the game through the Battle.net launcher, or on any of the frontrunning consoles, delete the game from the system and proceed toward installing it again. Download the relevant updates and try finding a match.
