Answer 1

Have you tried cleaning your Gradle?

Please try this command cd android && ./gradlew clean run this command on your project's root directory! or ./gradlew clean in your project's android folder.

after that recompile the App .

If the above solution does not help, try building your release with this command, go to your android folder and run command ./gradlew assembleRelease -x bundleReleaseJsAndAssets

Answer 2

The following command works for me:

gradlew assembleRelease -x bundleReleaseJsAndAssets 

Answer 3

Try to install Watchman

Then cd android && ./gradlew app:assembleRelease
