Using the Flogger library with the latest Android Studio Koala Feature Drop | 2024.1.2, AGP 8.6 causes this crash.

Not seeing before updating the Android Studio and AGP.

Could you please share some more details like

1. how the logger was configured
2. the log call that triggered this
3. the class/method containing the log call

Maybe there's some ProGuard magic going on that rewrote the class?

[chaoren]

Looks like the enclosing class that the logger is trying to find is just com.myapp.utils.DebugLogger.
