I tried to build test project to know, what i can, before creating real project. But i had a problem with build project for android in aab.

Remove the “Mobile Notification” Package your problem will solved.

In the “Package Manager” (Windows => Package Manager)
Just Remove “Mobile Notification” or “Mobile” Package.

If you are using Unity “Mobile Template” project, Unity Notification package may have some issue.
