I did it! I just removed & installed again create-react-native-app. npm uninstall -g create-react-native-app npm i -g create-react-native-app

I can’t believe that it works. @mirth have you solved your problem?

Hey quick comment,

I was running into the same issue, turns out I changed the node version using nvm and was getting the exact same error. So make use you get back to your project with the previous version. It did work for me.

cheers
