I am using yarn, and yarn android command in order to run the app in android simulator nox player. I couldn't run the app due to below error.

Windows 11:

Resolution: In package.json file I have changed "main": "index.js" to "main": "node_modules/expo/AppEntry.js" it worked for me.

It would be great if this solution helps anyone, let me know for any additional information.
