Also happening when changing the device orientation or resizing the window in Mac Catalyst.

happening on reload the app, this is happening since 3.9.0 i think

[yuriiburov]

The same problem
maybe downgrading react-native-reanimated to 3.9.0 would be a solution to the problem

Edit: It's working for me😁

[daxaxelrod]

Confirmed its happening to me too.

See that uiBlockWithLayoutUpdateForRootView hasn't been updated in a while but there have been other changes here recently. Mind taking a look @tomekzaw?

[jgiunta1]

Same, please fix

[karam1ashqar]

A pull request was merged, waiting for the release @jgiunta1

[tomekzaw]

At first glance, this looks like a different bug than the one with [REAAnimationsManager clearSharedTransitionConfigForTag:], starting the investigation right now

[tomekzaw]

I was able to reproduce this issue on cea5dff by pressing r in "[SET] Card" example:
