When clicked on reload app crashes and lost connection to debugger.

Tried uninstalling and reinstalling apk in emulator and cd android ./gradlew clean.

Still same error.


I have faced same issue and it was due to the 'react-native-reanimated' package (It's mentioned in their documentation that remote debugging is no longer possible for react-native-reanimated : React Native Reanimated Known problems and limitations) and the solution is to use flipper to debug : Debugging React Native apps with Flipper
