java.lang.IndexOutOfBoundsException: index=2 count=0 on Android

[jacobarvidsson]

Description

We are getting this error when react native is initialising (app start). We started seeing this after upgrading from react-native 0.73.8 to 0.74.5. We have tried several react-native-reanimated versions, 3.8.0, 3.14.0 and 3.15.1.

The issue is difficult to reproduce manually but happens on every other PR running our automated appium tests on Saucelabs. The issue does not seem to happen to every device, but mostly pixel devices running android 12.

The issue has previously been reported here: https://github.com/software-mansion/react-native-reanimated/issues/3856 however the issue is not the same as the author describes, though it is the same issue as several of the comments mentions.

Issue seems to happen on multiple react native and reanimated versions. Some comments seems to hint on the fact that LayoutAnimations could be the cause, however we are able to reproduce this even with LayoutAnimations disabled.

Steps to reproduce

1. Start the app, the issue appears as soon as react-native is loading.

Hey! 👋
