RCTBridge required dispatch_sync to load RCTAccessibilityManager. This may lead to deadlocks

Description

When building a new project with React Native 0.73.3 I am getting the warning RCTBridge required dispatch_sync to load RCTAccessibilityManager. This may lead to deadlocks as soon as my app starts.

I tried creating a new app with version 0.73.2 and this warning disappears

This my package JSON file:

Getting the same after upgrading to 0.73.3, @fabOnReact care to explain why you linked the comments above?

Also getting the same after upgrading to 0.73.3 and I don't have the issue with 0.73.2 either.

after applying a patch from PR and PR the issue is gone

@cipolleschi

@cipolleschi can you look into this (potentially related to f39f34e)

Fixed already:

Pick requested in 0.73.4 => [RN][iOS] Fix warning when loading RCTUIManager and A11yManager #42734
PR for main => Fix warning when loading RCTUIManager in the old architecture #42733

"react-native": "0.73.3" still same

I have the same issue.

"react-native": "^0.73.2",

When 0.73.4 version with fix will be released ?

Me too:

Creating a project now using:
npx react-native init MyProject --template react-native-template-typescript

this downloads 0.73.3 RN version, and then without any modification, I get the error in IOS.

Waiting this new PR approved in 0.73.4 or whatrver. Thank you

Version 0.73.4 with the fix with be released Monday!
In the meantime you should be safe ignoring that warning.

Sorry for the inconvenience

@Titozzz
