App Crash - UIViewControllerHierarchyInconsistency

See original GitHub issue

Bug

When i open the app, it crashes sometimes ( %20 crash rate ) There is no log on console, Flipper can’t catch any error, Only Crashlytics catches the error.

Android is working very well.
There is no problem on version 3.3.0

This seems to have to reappeared (5.4.0 + iOS).

Exception thrown while executing UI block: A view can only be associated with at most one view controller at a time! View <RCTView: 0x7fe85544df90; reactTag: 7413; frame = (0 0; 0 0); layer = <CALayer: 0x6000002f6180>> is associated with <UIViewController: 0x7fe8550becb0>. Clear this association before associating this view with <UIViewController: 0x7fe854f78b50>.

I narrowed down the problem in my case to version 4.1.0.

4.0.1: works as expected 4.1.0: throws the ViewController error above and the app crashes.
