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

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.
