Probably the use was created tables before, and only then make the class abstract. The django-polymorphic itself does not allow to have base abstract classes

Find that permissions is not create for the abstract classes by Django, but in case if they created manually, everything works fine https://github.com/django-guardian/django-guardian/issues/778#issuecomment-2098279253
