Im facing this error when trying to generate signed apk / bundle in android-studio. Im using Android Studio Giraffe to build this project.
Event the projects runs in the emulator correctly and Rebuild project is also successful.
My assumption is the some of my dependency is generating duplicate classes but i was not able to find the specific one.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
from your error here i can tell that you have 2 versions of kotlin standard library in included. check if you have added two different versions somewhere
