Project keeps flipper java file under app > source > debug in react native > 0.62. There is an issue with Flipper Network that causes the problem in your case. If you remove the debug folder, you will not be able to debug Android with Flipper, so the best solution is upgrading Flipper version in android > gradle.properties to 0.46.0 that fixes the problem.

You can change it with this line FLIPPER_VERSION=0.46.0
