Thanks for the report - do you have any reproduction steps?

Nevermind, this has been fixed and will be available in an upcoming release.

An unfortunate side effect of this seems to be that the adapter is set to null before any pending fragment animations are completed.
In my project I add a PreferenceFragmentCompat to the backstack, specifying custom enter and exit animations. Now, when the user presses the back button I call FragmentManager.popBackStack() which in turn starts the custom exit animation.
The problem is that popBackstack() internally calls onDestroyView() on the PreferenceFragmentCompat to be removed. The PreferenceFragmentCompat calls unbindPreferences() which calls getListView().setAdapter(null).
The effect is that the list of preference items is cleared instantly before the exit animation even starts! This causes a white flicker and is clearly noticeable, the preference items disappear, then the view fades out.
Could you prevent setAdapter(null) from being called in this scenario? Maybe unregister the data observer instead?

Since the
Please file a bug against Fragments the with a sample project that reproduces this issue and we will be happy to take a look at what's going on.

I can confirm that using fragment 1.2.2 resolves the issue, thank you!
Without an explicit dependency declaration version 1.1.0 was still used (transient dependency of appcompat 1.1.0).

Mention the current destination in getBackStackEntry errors
Improve the debugging experience for "No destination
with ID..." errors in getBackStackEntry() by mentioning
exactly destination the NavController is on. This would
allow developers to know if they have called popBackStack()
to a destination they don't expect to be at or if
they have not called setGraph() at all (where the
current destination would be null).
Test: existing tests pass

Description
Version used: 2.3.0
While using `by navGraphViewModels`, my crash reporting reports an error when invoked
NavGraphViewModelLazy.kt line 56
Fatal Exception: java.lang.IllegalArgumentException: No destination with ID 2131296839 is on the NavController's back stack
at androidx.navigation.NavController.getBackStackEntry(NavController.java:1293)
at com.example.ExampleFragment$$special$$inlined$navGraphViewModels$1.invoke(NavGraphViewModelLazy.kt:56)
[...]
This is difficult to debug since the navGraphId that I pass in should theoretically always be in the NavController's back stack when navGraphViewModels is invoked. The error message could be improved by letting me know what IS available on the back stack or if the back stack is completely empty.
