Description

I customized a Modal component using the Animated.View component with entering and exiting props. When the Modal closes and navigates to another screen, the app crashes with the error: java.lang.NullPointerException: Attempt to read from field 'int android.view.View.mViewFlags' on a null object reference in method 'void android.view.ViewGroup.dispatchGetDisplayList()'.
I tried removing the exiting prop, and the crash didn't happen.
Not all devices crash—most crashes are related to Oppo/Realme, etc.

Steps to reproduce

1. create a project with expo (npx create-expo-app@latest)
2. reset project (npm run reset-project)
3. install dependency (npx expo install ahooks react-native-get-random-values uuid react-native-keyboard-controller react-native-paper)
4. prebuild (expo prebuild)
5. add two screen (index and test)
6. add Modal component
7. add a button to open a drawer on index screen
8. navigate to test screen on Modal callback "onConfirm"
9. build a release app and install to a device (oppo or realme)
10. open the app in default index screen, click the button to open the drawer and then click the action
11. the screen change to test screen and then the app crash
