Method 3: Reinstall Roblox Sometimes the problem can already be caused by a corrupted game file. To fix this you will have to uninstall the game then install a fresh version from the Microsoft Store.

To do this, open Microsoft Store, search for, download, and install Roblox on your PC. Launch the UWP version of Roblox, sign in with your account and see if the problem is now fixed.

If you get the Failed to create directory message with error=3 when starting Roblox on your Windows PC, use these proven fixes.
