React Native is like that. You suddenly come across unknown type of errors all the time. This might be related with react native version update or not.
So here is the fix for react native error: bundling failed: Error: Unable to resolve module ‘@babel/runtime/helpers/interopRequireDefault’
What you all need is to open command prompt / terminal and execute npm add @babel/runtime and run the app again.
