Expected results: No crashes, app behaves properly

Reproducible with versions: 6000.7.0a1, 6000.6.0a1, 6000.5.0a7, 6000.4.4f1, 6000.3.17f1, 6000.0.79f1

Not reproducible with versions: 6000.5.0a6

Tested on (OS): Windows 11, Android 14, Android 17

Notes:

On Unity build before AGP update same project runs fine (tested with 6000.5.0a6)
Providing a custom proguard file seems to solve the issue. Attaching an example proguard (made with help of AI) that makes the project build and run
