Xbox Game Bar suddenly not working with PowerPoint

I have the same problem. It works sometime but fail sometime.

If you have your PowerPoint open on full screen to begin with and then hold down the
Windows Key + G, the game bar will appear. From here, click record and it should work fine.

That used to work, but not anymore, tried restarting, doesn’t work.

Ah okay, apologies. I did try it today and it worked okay.
