Stack trace: 

.lang.NullPointerException: Attempt to invoke interface method 'java.lang.Object kotlinx.coroutines.flow.Flow.collect(kotlinx.coroutines.flow.FlowCollector, kotlin.coroutines.Continuation)' on a null object reference

Start by reproducing the immediate crash from the F-Droid build on the Amazon KFSNWI running Android 11. Trace the null Flow reported through kotlinx.coroutines Combine.kt:45 and identify the app source that supplies it. Done means the app launches on this device without the crash and the failure is covered by an appropriate regression check.
