Found the issue, ugh
Noticed that when I do the following:
transaction.addToBackStack(null)
When adding a Fragment with ViewPager2, the above issue occurs, although, idk if it's becaugh of gcFragments() anymore.
As soon as I un-comment that line, the issue disappears.

Is the Sample application, to reproduce, move back really fast between page 2 -> 1 and vice versa (they are bottom buttons) a couple times.
Wait a couple seconds and page 1 (the black page) should turn white meaning the Fragment has been removed.
As soon as you comment line 40 on MainActivity, and attempt again, the error does not persist

Woops, sorry, If you guys had the previous ViewPagerCrash test app, I forgot to push (was exhasuted after debugging) I pushed one more time for the latest reproducible code

We'll have a look, thanks for reporting and repro steps / sample app. Stay tuned for updates on this issue.
Description
'com.android.support:appcompat-v7:28.0.0'
'com.android.support:design:28.0.0'
Version used: 28.0.0
Theme used: Theme.AppCompat.Light.DarkActionBar
Devices/Android versions reproduced on: Nexus 6 running API 27
If we set a Propagation (Tested only for SidePropagation) on a support transition which has a start delay, then the propagation isn't respected when animating the views out (but is when animating the views in).This is in contrast to the native implementation of this feature, where it works correctly when animating in, or out with a start delay.
- Relevant code to trigger the issue.
//support transitions
android.support.transition.SidePropagation propagation = new android.support.transition.SidePropagation();
propagation.setSide(Gravity.END);
android.support.transition.Transition propagatedTransition = new android.support.transition.AutoTransition();
//Using a start delay causes the support version to not propagate the transition when animating out
propagatedTransition.setStartDelay(150);
propagatedTransition.setPropagation(propagation);
android.support.transition.TransitionManager.beginDelayedTransition(rootViewGroup, propagatedTransition);
toggleChildren(supportLayout);
- A screenrecord or screenshots showing the issue (if UI related).
Attached is a screen record of it. I've also attached a sample project. Simply tap the green (native - working) box to trigger the transition using the native Transition API, and the red (support - broken) box to trigger the transition using the support Transition API. You may want to make the transition longer and change the propagation speed to make it more obvious (e.g. 0.1f propagation speed)
