[com.innersloth.spacemafia] Signing in with Google doesn't work, loads indefinitely

Affected app
Name: Among Us
Package id: com.innersloth.spacemafia

Describe the bug
The game asks for Google account access and Play Games access. You can grant it access but after granting access to those it loads indefinitely. The game is unaccessible because it depends on Google login for Android users.

To Reproduce
Steps to reproduce the behavior:

1. Open Among Us.
2. Grant the game access to your account and Play Games.
3. Issue occurs.

Expected behavior
The login should succeed and the game should finish loading.

System
Android Version: 13
Custom ROM: One UI 5.1

microG
microG Core version: 0.3.6.244735
microG Self-Check results: All ticked

Additional context
I think this issue started occurring in a recent version of microG. I've tried hiding modules, Magisk DenyList and passing Play Integrity/SafetyNet and it won't load so I'm pretty sure microG is the reason why.

Start by reproducing the sign-in flow on Android 13 with microG Core 0.3.6.244735, following the listed steps and confirming the indefinite loading after account and Play Games access. Then trace the Google account and Play Games authentication handling; done means Among Us completes login and finishes loading instead of hanging.
