On earlier versions of Windows, users reported errors that resulted in Roblox not opening in Windows. The same error trickled down to Windows 11. If you’re experiencing Roblox freezes or crashes on your computer, here are the top five fixes to help you resolve the error.

Is Roblox compatible with Windows 11?

Roblox is compatible with all Windows versions, Windows 11 included. The application is natively supported by Windows 11, allowing you to crossplay with users from other platforms.

Why is Roblox freezing on my computer? 

There are several reasons why Roblox keeps crashing on PC. They include:

  • Outdated graphics driver: Roblox, like most games, requires graphics cards to operate. If your graphics card needs to be updated, Roblox might crash.
  • Insufficient RAM: if you’ve got too many running background applications, you’ll use up your RAM, which can cause Roblox freezing on Windows 11.
  • Firewall restrictions: Firewalls have a list of allowed applications. If Roblox isn’t on the list of allowed apps, it might cause the app to freeze.
  • Antivirus software interference: Similar to firewall restrictions, antivirus software can cause a Roblox crash if it flags any harmful tendencies in any of the app’s files.
  • Poor Internet connection: Roblox requires a strong network connection for the game to run smoothly. If Roblox keeps crashing on Windows 11, your network connection might be the cause.

  3. Repeat the process until you’ve closed all the unnecessary background apps.
  4. Relaunch the app to see if Roblox keeps crashing.
