Hi @janicduplessis, thanks for submitting this issue! I remember I've tried to fix this issue couple months ago (here, but this change has ended in revealing another issues with view traversing 😕 I'll try to find out what's going on here, thanks!

[RalissonMattias]

@tboba Is this problem similar to this one https://github.com/software-mansion/react-native-reanimated/issues/6222 ? Otherwise I can open a new issue

[tboba]

@RalissonMattias can't say if this issue is related to screens, as there's too few info attached in the original issue. Could you post us a full log trace from the error? Also, are there any errors printed in the JS console?

@RalissonMattias that's strange indeed. Are you trying to do something similar as in this issue (navigate to two different screens)? If not, I think you can post an issue with the reproducer, so we could check this error on our side.

[RalissonMattias]

@tboba Yes, I'm trying to navigate to two different screens, but using tab navigation. A curious fact is that when I use react-native-reanimated in version 3.12.1 the application does not break, however when I use react-native-reanimated in version 3.13.0 the application breaks. That's why I initially posted the issue on react-native-reanimated

[Titozzz]

https://github.com/Titozzz/crash-screens-tabs-new-arch @RalissonMattias this is a repro for your bug (and mine) It actually related to Reanimated 🤯

[janicduplessis]

I actually just hit that bug too, I can confirm it is a regression in reanimated v3.13.

[janicduplessis]

I do not think they are related tho

[dppo]

The same problem in react-native-reanimated v3.13, and it became normal after use v3.12.1.

[tboba]

Looks like https://github.com/software-mansion/react-native-reanimated/issues/6222 has been reopened, so for further discussions about the bug with bottom-tabs, please head over there.

[tboba]

I can confirm this issue is reproducible 🫡

[tboba]

Hey hey @janicduplessis, could you try to get screens from branch @tboba/fix-screen-traversing and check if everything works fine on your side? 😄

[janicduplessis]

@tboba Works fine now, thanks!

[kkafar]

I wonder whether we should pursue reporting this to RN team & trying to fix this upstream. Since there is a discrepancy between Paper & Fabric updates batching I believe this could be considered as an unintended change, similarly to this one.
