Reanimated Stops Working Completely on iOS

phantom-xrn commented 1 month ago

Description

Reanimated completely stops working after a while on production on iOS. I've attached a video and a minimum reproducible repo.

Some thoughts:

This bug occurs 100 out of 100 times with Video but if you remove it, it only happens around 1 out of 100 times.
Occurs with both react-native-video and expo-av.
Once the bug occurs everything that touches reanimated stops working but everything else including the native Animated API works fine.
Only occurs on iOS on release mode on actual device.

Steps to reproduce

Clone https://github.com/phantom-xrn/reanimated-bug/tree/main

Run it on release mode on an 120hz iOS device(Replicated on 14 pro/15 pro/15 pro max but not on 12 mini/13)
Wait for the video to start playing.
Press and Long Press on the bottom two cards a few times.
Reanimated will stop working after a while. The buttons will not scale anymore when pressed and any component that uses reanimated like bottom sheets stop working.
Only error on Xcode console is Unbalanced calls start/end for tag 19

Just added a $512 sponsorship and am happy to pay $128/hour for the time to fix this. This is affecting us in production and would really appreciate if you guys could prioritize the issue.

Hi @phantom-xrn

I prepared a PR #6442 that should resolve this issue. We might need some time to get it merged, since it has to do with an important part of our logic. Until then you can use this patch on your app. react-native-reanimated+3.15.0.patch

@phantom-xrn We just published a new version of reanimated (3.15.1) that includes this fix.
