Can you check Godot 4.3 RC 2? There were some issues about memory leaks and crashes fixed on Android.
ObjectDB instances leaked at exit is definetly a weird one, could have been fixed in 4.3 too though.

Tested with 4.3 , issue persist and seems now app not quite on mobile back press just hang on embedded view screen.
