This happens in Activity_Resume, when programs rebuilds a form.
Sub Activity_Resume calls another soubroutines, which can call another subroutines.
All subroutines have the same layout ( Try .... Catch Starter.Clog). Crashlytics shows exception in Activity_Resume, but Crashlytics's log shows an error in latest subroutine, which I call (indirectly) in Activity_Resume event.
A problem that I am not able to reproduce this error on own phone.
Crashlytics talks that affected 0,5% of users. 88% of crashes is under Android 10, 12% - under Android 9. Mostly cheap models. Maybe not enough memory ?
