I came across this issue today. Read a few SO posts and saw one guy mentioned if your app launches and hangs on the splash screen and then crashes with no error it probably has something to one of your npm dependencies.

After digging deeper i saw the react packager was throwing the error

This error is caused by a @providesModule declaration with the same name across two different files.

2. rm -rf node_modules

3. rm -rf $TMPDIR/react-*

4. npm i
