I had the exact same problem, but for me it was a very simple issue. The Xbox app on PC logged me out for some reason, and I kept getting stuck on the loading screen, "Press any key to start", but after logging in, it loaded up fine for me.

Cant login into the xbox beta app on windows

when i click on login any login icon it went grey and then back on the xbox beta app

same in the game bar i cant log in

that pretty bad if you wann play forza but you need to be logged in for it

Sorry to hear it. After you've switched your primary address it can take a few days to fully populate your account which may be why you're having trouble.

Once you've done it please try deleting the Beta app then log out of the Xbox Console Companion app on your PC. Restart the PC and log in to your Xbox Companion App before redownloading the Beta app. Let me know if that works

I have the same issue. No errors when signing in, just goes through the motions. I click on lets play button after signing in and it shows that im not logged in. I also cant play any games through the app. Get an error that i'm not logged into xbox.
tried reinstalling the xbox pc beta app, and the xbox identity provider app, restarted pc, and still not fixed.
