I have Windows 10 (64-Bit), and the recording software it came with (gamebar) doesn't work correctly.
If I try to open it using WindowsKey + G it just says "Can't Record Right Now, Try Again Later"
Also, the Troubleshooting page for the Gamebar does Not have the Answer to fixing this, I've already checked
Fix problems with Game bar on Windows 10.
Let us know how it goes.
Any of those tips didn't help either.
Its only when I try to record minecraft since its fine with some other games I play.
