How To Fix Roblox Keeps Crashing In 2023

Having trouble with Roblox crashing on startup? Read this guide to discover effective solutions and troubleshooting tips to fix the issue.

Roblox keeps crashing repeatedly for many PC players for no apparent reason. While some players might be able to play Roblox for a while before it crashes, others encounter Roblox crashing on startup. This has sparked discussions among the Roblox community, with players being rather perplexed as to why this is happening. The puzzling part is that Roblox is known for running smoothly on even the most low-end PCs, which makes this issue even more confusing.

Key Takeaways
  • Roblox can crash for various reasons, including corrupted or missing game files, conflicts with antivirus software, or inadequate system hardware.
  • Firstly, verify that your PC is not older than five years and has a CPU with a clock speed equivalent to 1.6 GHz.

  • Follow all of these solutions to stop Roblox from crashing:
    • Disable your antivirus software and see if the crashing issue has been resolved. If it is, add Roblox to the exceptions list of the software.
    • Verify the Roblox game files from Windows 10 and set Roblox as a high-priority game using Task Manager.
    • Finally, delete the Roblox cache folders and turn off fullscreen optimization mode.

Why Does Roblox Keep Crashing?

There can be several reasons why Roblox keeps crashing. While Roblox can run on many low-end systems, in case your PC is extremely old and you are trying to run Roblox on high graphic settings, crashes will be inevitable. On the other hand, if your PC is relatively strong but has low storage space, you will also encounter crashing. The crash itself will accompany an error message like this:

A few more reasons can include corrupted or missing game files, conflicting updates, or outdated GPU drivers. The most common cause behind a game crashing is usually insufficient system hardware. While that is usually not the case with Roblox, you should quickly review its system requirements and confirm whether your PC meets them.

Minimum System Requirements

These are only the bare minimum system requirements, and it is always recommended to have hardware better than this.

GPU: A dedicated GPU not older than five years.
CPU: Recent CPU with clock speed equal to or greater than 1.6 GHz.
OS: Windows 7, Windows 8/8.1, and Windows 10. Windows 8/8.1 will require Desktop mode.

How To Stop Roblox From Crashing

There is no single fix to any crashing problem, as the causes are countless and sometimes unrelated. Although you can fix the crashing according to what is causing it, knowing the specific culprit can be incredibly difficult. Therefore, you must keep trying all the various solutions mentioned in this guide until your crashing issues stop.

Before moving on, make sure to confirm if your GPU’s device drivers are updated. Outdated drivers are often the reason behind Roblox crashing. If there is an update available for your GPU’s drivers, you should download it immediately. After downloading, restart your PC and see if the crashing has stopped.

In case the crashing continues, remain calm and thoroughly try out all of these methods:

Disable Windows Defender Firewall

So far, this seems to be the most effective solution for the crashing issue. Though, it can appear a bit confusing at first because antivirus software like Windows Firewall is supposed to protect you from foreign threats or malware. This is true as long as the antivirus software does not misinterpret a safe and trustworthy application as a potential virus. If this happens, the application will be restricted from performing any actions, including the ability to start.

In our case, if the antivirus software is the culprit, you will specifically notice that Roblox keeps crashing on startup. Firstly, it is important to confirm whether your antivirus software is indeed putting restrictions on the Roblox application. To do this, you can simply disable the software and then launch Roblox to see if the crashing stops. 

Here is how you can disable Windows Defender Firewall:

  1. Access the start menu by pressing the Windows button on your keyboard. Now click on the gear icon to enter the Windows settings.
  2. Here, click on Update & Security to enter the Windows Security section.
  3. In Windows security, click on Firewall & Network Protection
  4. You will see a new security window open. Here, disable the firewall for all three networks you see on the screen.

If there is any other antivirus software on your system, you should disable it similarly. Once disabled, you should launch Roblox and see if the crashing stops. If it does, then you have found your culprit. Of course, it is not a good idea to keep them disabled forever. Instead, you should add Roblox to the exceptions list of your antivirus software. In case the crashing persists, you can skip this second step and move to the next method.

Add Roblox To The Exceptions List

Adding Roblox as an exception in your antivirus software will let it know that this application is not a threat. This step is crucial because if you keep your antivirus software disabled for a long time, it will expose your PC to all types of dangerous viruses

This is how you can add exceptions in Windows Defender Firewall:

  1. Follow steps 1 and 2 in the previous section to reach Windows Security.
  2. Here, click on Virus & Threat Protection. This will open a new window.
  3. Find Virus & Threat Protection once again in this new window. Once found, click on Manage Settings right under it.
  4. Now scroll down until you find Exclusions. Here, click on Add or Remove Exclusions. This will open the window where you can add exclusions.
  5. Click on Add an Exclusion and select Folder. Then add the Roblox folder to this list.

Repeat the same process with any other antivirus software, and you will eliminate the issue of Roblox crashing on startup.

Repair Roblox App Files

Roblox App might get corrupted, which is a common reason why Roblox might be crashing. The smooth operation and even the functionality of a game completely rely on its files. Therefore, if these files are corrupted or missing, your game will likely not be able to operate as intended. Your game files can get corrupted without your knowledge, usually because of an incorrect download. There is also the possibility that the files were accidentally deleted by yourself or another program performing a cleanup.

Regardless, the solution is very straightforward. Windows has a built-in tool for this scenario to verify and repair any missing or corrupted files. Follow these steps to fix your Roblox files:

  1. Get to the start menu by clicking the Windows icon on your desktop. Then click on the gear icon to open the Windows settings.
  2. Inside the settings, click on the App section to open a list of all the applications available on your PC.
  3. Find Roblox from this list and then go to its Advanced Options.
  4. Now find the reset section and click Repair to verify the Roblox game files.

Set Roblox PC App As High Priority

Giving high priority to Roblox will tell your PC to allocate more processing power to it. Your PC will quite literally prioritize Roblox, which can potentially stop Roblox from crashing. This method will prove to be especially effective for players with low-end PCs. While this method is not as effective for players with relatively strong PCs, it is still worth attempting.

Here is how you can set Roblox as a high-priority application:

  1. With Roblox App launched, right-click on your taskbar and open the task manager.
  2. Switch to the processes tab to open a list of all active operations.
  3. From here, right-click on Roblox and select Go to details.
  4. In the details section, right-click on the Roblox application again and highlight the set priority option.
  5. You can now select High to make Roblox a high-priority application.

Clear The Roblox App Cache

A cache folder by itself is not a bad thing because it can help an application recall information faster. This means that the application will perform tasks more efficiently while operating fluidly. Though this is not always the case, as an excessive amount of cache build-up can have the opposite effect. As such, Roblox may be crashing because of too much unnecessary cache. It is always a good idea to clean your cache folders now and then. 

Follow these steps to clear the Roblox cache:

  1. Press the Windows button + R on your keyboard together to open the run prompt.
  2. Here, type %Temp%\Roblox and click OK. This will take you to the Roblox cache folder.
  3. Select everything in this folder by pressing CTRL + A simultaneously. 
  4. Now right-click anywhere while everything is selected, then delete.

Disable Fullscreen Optimization

With fullscreen optimization enabled, Roblox will run in a borderless fullscreen mode. This feature is enabled by default in Windows and is supposed to help your games run more smoothly. However, this is not always the case, as fullscreen optimization is notorious for causing various crashes. Therefore, it is always a good idea to keep it disabled. This will eliminate the possibility of fullscreen optimization being the cause behind Roblox crashing on startup or elsewhere. 

Here’s how you can disable Fullscreen Optimization:

  1. Find the Roblox application and right-click on it. From the list of options, click on properties.
  2. Make sure you are in the compatibility tab in properties.
