When minifying a project that uses Leanback (View-based) with the version of R8 that is included with AGP 8.10.0-alpha04, I get the crash that is included below.

This only happens when minifyEnabled is set to true and debuggable is set to false.

If I use AGP 8.8.0 then the app doesn't crash.

I have attached a project that can be used to reproduce the issue (it's basically the Leanback template that's in Android Studio with some small modifications).

Crash log:
