Sorry,
I was away for over 2 weeks and just reading the forum.
To create an AAB from an APK you need the CLI of Android Studio or any other tool. It has 2 stages:
1 - Getting a security code (keystore)
2 - Converting the APK to AAB using this security code as a signature.
Let me know which part you need help.
I am a user who is also experiencing this exact issue. Have there been any developments since October, or solutions?

After testing I found a workaround.
I shared via intercom a new copy project of yours so that it doesn’t have any issues.
Let me know if that works for you

Your workaround fixed it for anyone else who experiences this issue. I had to update “Firebase, In-App purchase keys, your App (Bundle) ID, version code&name, and import your Android Keystore.” and then it functioned perfectly!
