Thanks for the detailed analysis. This may not be an issue anymore since we've started using Main.immediate there but I' not sure; I'll try to create a test case.

just emitting same live data reproduces the issue.
@Test
fun raceTest() {
val subLiveData = MutableLiveData(1)
val subject = liveData(testScope.coroutineContext) {
emitSource(subLiveData)
emitSource(subLiveData) //crashes
}
subject.addObserver().apply {
testScope.advanceUntilIdle()
}
}

testScope.advanceUntilIdle()

Description
The equality check in `hasMatchingArgs` for Array NavTypes erroneously checks for object reference when it should check array content.
This fix is required for existing NavControllers functions as well as upcoming NavController APIs for Safe Args.
