Reproducible Demo
No idea how to reproduce as occurs randomly in release builds. The stack trace is from Crashlytics. Seems to be related on how React Native updates the UI. Our code does not have much control over the native screen updating and as JavaScript is single threaded, there isn’t much we can do about concurrency.

A nice way to get rid of bugs without fixing them. As nobody has mentioned a fix in the next RN version, it probably does not exist.
Testing with the new RN is not currently possible as it has compatibility issues with my dependencies (or for some other reason does not work at all).
Getting this on android only:
All bugs related to this end up getting closed with no without a solution!!!
