Crash report

Version: 0.16.2
Device: Google Pixel 10 Pro
System: Android 17 (API 37)

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
	at kotlinx.coroutines.flow.internal.CombineKt$combineInternal$2$1.invokeSuspend(Combine.kt:45)
	at kotlin.coroutines.jvm.internal.BaseContinuationImpl.resumeWith(ContinuationImpl.kt:9)

Start with the Feed Sync area of the Android app and trace the Flow inputs involved in the kotlinx.coroutines.flow.combine call shown at Combine.kt:45. The report has no reproduction steps or project file/test reference, so first establish whether the launch crash reproduces on Android 17 with version 0.16.2. Done means the app launches without this NullPointerException and feed sync still works.
