I have a game built with Godot 3.5.2

The .apk files are smaller than 15mb and I have added the metadata and dependencies according to the documentation:
Google Play Instant | Platform | Android Developers

The game works fine when installed normally but crashes after the bootsplash when started via the "try now" button.
The error logs indicate a crash, but it's difficult to pinpoint the exact cause of the crash.

adb logcat -s godot shows me this:

It seems like there are more steps involved into making a godot android export usable for Google Play Instant. Anybody know what that could be ?

this issue is caused due to Add Support for Android Play Asset Delivery
compiling android application utitlizing installTime play delivery. We can overcome this issue by reverting this commit for the google play instant builds in the godot source code and compiling a custom engine.
