React Native: Can't run app on iOS correctly "Failed to load bundle(http://localhost:8081/index.bundle?"

When trying to run a react native iOS App, I am getting a red page with an error. This is the following error I am getting on the iOS screen.

 Failed to load bundle(http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false) with error:(Unable to resolve module ./node_modules/react-native/src/constants/screens from/Users/username/Desktop/mobile/App.js: The module ./node_modules/react-native/src/constants/screens could not be found from /Users/username/Desktop/mobile/App.js. Indeed, none of these files exist:

/Users/username/Desktop/mobile/node_modules/react-native/src/constants/screens(.native||.ios.jsx|.native.jsx|.jsx|.ios.js|.native.js|.js|.ios.js|.native.js|.js|.ios.json|.native.json|.json)`

I tried resolving this issue by looking at other stackoverflow posts. However, none of the solutions worked for me so far. I am honestly confused and don't know what to do. Any help or suggestions are appreciated.

Quick fix: npm add @babel/runtime

then: rm -rf ios/build/; kill $(lsof -t -i:8081); react-native run-ios
