Hello Chip._,

Thank you for posting in the Microsoft Community.

I understand that you are having trouble launching Roblox on the latest Windows OS build. This seems to be a compatibility issue between Roblox's anti-cheat system and the new Windows OS overlay feature. We apologize for any inconvenience this may cause you.



As a possible workaround, you can try disabling the Windows OS overlay feature by following these steps:



- Press the Windows logo key + G to open the Game bar settings.

- Click on the Settings icon on the right side of the Game bar.

- Under General, uncheck the box that says "Enable Xbox Game bar for things like recording game clips, chatting with friends, and receiving game invites".

- Restart your PC and try launching Roblox again.



We're looking forward to hearing from you. If there are any inquiries about our description or if there are any misconceptions, do reply to the post.

There is no way to disable the overlay, so im unable to play roblox, crappy windows

Thank you for understanding.

oh, okay! Thank you but, do you know why Roblox used to work before I downloading it on Windows 10?

While some games can be run on ARM CPU's, a recent update added an anti-cheat software called Byfron to the Roblox UWP (Universal Windows Platform) application. The game no longer works because this Anti-cheat software does not support ARM CPU's yet.

Due to this update, it won't work in Windows 10 either.
