Grounded 2 (Steam): Infinite loop when trying to log in with Microsoft account

[joereim]

Hello! I own Grounded 2 on steam and also subscribe to Xbox PC Gamepass. I am trying to play the game with my child by having them log in using my steam copy and I am playing with the gamepass version via the Windows Xbox app. When trying to sign in with their Microsoft account, it is giving me an endless login loop. I type in their password and it accepts it, spins, and then goes back to asking which method to login with (biometrics, password, or email code). I have tried password and email code and they both do the same thing.

Please help! I bought this copy on Steam purely so that I can play with my child and it is not working at all. The first game works just fine in this manner!

Thanks!
