After upgrading one of our apps to target Android SDK 29 we are detecting in firebase crashlytics that around 0,5% of our users (we have +100k daily users) are having randomly this Crash, no matter the activity. All our activities extend AppCompatActivity, and the crash happens at "super.onCreate" so it's all related to internal Android code, not ours, we are not iterating or modifying any list. It happens mainly on Android 9 (>80% of occurrences). We suspect that the culprit is a bug on any of the Androidx dependencies. Has anybody had to deal with this rare crash too?
