Possible Duplicate of this question. Try running this command from root directory of your project.

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

it returns error ENOENT: no such file or directory, open 'android/app/src/main/assets/index.android.bundle'. Run CLI with --verbose flag for more details. – Umer Oct 07 '20 at 10:33

I encountered the same problem.

I resolve this, by deleting the dependency in android\settings.gradle file. That not specified in the build.gradle file.

This fix my problem. Hope this helps you.

A source of the issue can be import com.facebook.react.BuildConfig; in MainApplication.java. Removing that may help.
