An old instance of the remote debugger running caused this for me. Not sure of the "whys", but if you want to kill the debugger programmatically, add this to the top of your App.tsx or whatever your top-level entry file is:

import { NativeModules } from 'react-native';
NativeModules.DevSettings.setIsDebuggingRemotely(false);

I got same error, but all going well after I yarn global remove wml

yarn global remove wml

that save my life

if you have never install wml, just consider some other related global libs

----update----- I got the error again even I uninstall wml staff, but I found my issue's root cause was the watchman, after run brew uninstall watchman, all going well

If you are using create-react-native-library for native modules and getting this error. Do the following:

  1. cd example
  2. npx react-native start
  3. In rootDir, yarn example run

Replace this code in `MainApplication.java

        @Override
        protected String getJSMainModuleName() {
          return "src/index"; <---add this
        }

Apparently there's an issue with moving index.js to src/index.js. I moved it back to the project root and it's working fine now.
