RNScreenContainer crashes on iOS while in the background

See original GitHub issue

Description

RNScreenContainer crashes, as per below, while the app is in the background. The error happens at random times (i.e. not immediately before/after backgrounding the app), presumably when our background task kicks in. I unfortunately haven’t been able to reproduce yet…

If it help, we are also experiencing the exact same crash.

Same as above most crashes happen after app comes to foreground from background.

We are currently using: react-navigation/bottom-tabs:@5.11.8 react-navigation/native@^5.9.3 react-navigation/stack@^5.14.3 react-native-screens@3.1.1 react-native@0.64.0 react@17.0.1

Edit: we’re seeing another issue related to this

EXC_BAD_ACCESS Exception 1, Code 458777608, Subcode 8 > Attempted to dereference garbage pointer 0xa5991b586408.
