Why does this error appear when building release build and causes crash but not with emulator or usb debug?

Question

I am having an issue where the application that is build using ./gradlew bundleRelease (aab) or ./gradlew assembleRelease (apk). At the moment when user clicks the application it crashes straightaway and this issue doesn't happen on emulator when building the application using npx react-native run-android or using the real device through usb debugging.

In the google play developer console I got the following error that shows up

FATAL EXCEPTION: create_react_context
Process: com.vahingonsattuessa, PID: 18803
java.lang.RuntimeException: Unable to load script. Make sure you're either running Metro (run 'npx react-native start') or that your bundle 'index.android.bundle' is packaged correctly for release.

And

Any ideas why this happens and how would I be able to fix this?
