The offending PR is #3555. Fixed in #3698.

If you encounter warning “RCTBridge required dispatch_sync to load REAModule”, you have four options:

1. Simply ignore the warning (it only appears in debug mode, so you won’t see this in production build of your app).

2. Add the following code in index.js of your app:

import { LogBox } from 'react-native';

LogBox.ignoreLogs(['RCTBridge required dispatch_sync to load REAModule']);

1. Remove the following lines in node_modules/react-native-reanimated/ios/REAModule.mm (e.g. using patch-package):

- + (BOOL)requiresMainQueueSetup
- {
-   return YES;
- }

1. Downgrade to react-native-reanimated@2.10.0 and upgrade to 2.12.0 once this issue is fixed.

I can also confirm that moving from 2.10.0 -> 2.11.0 introduced this issue.
