I’m trying to package a build of my project to upload to the Google Play Store. I need an AAB file for Google Play. Whenever I try to package the project with “Generate bundle (AAB)” enabled in Platforms–>Andriod–>App Bundles, the will always get a “Packaging failed!” result and it will say “PackagingResults: Error: Unknown Error” in the log.

I think I’ve isolated it to this singular thing being enabled. When its not enabled, I get get a build just fine and run the APK file on the phone. I’m packaging on “Development” on Andriod (ETC2).
If anyone knows what’s going wrong I would greaty appreciate it
