Django Superuser Permission Issue: "You don’t have permission to view or edit anything"

I'm encountering an issue in my Django project where I'm unable to access the admin site as a superuser. When I try to log in as a superuser, I receive the error message: "You don’t have permission to view or edit anything." I've followed the standard steps for creating a superuser and configuring my custom user model, but I can't figure out why this permission issue is occurring.

  Site Administration, You don’t have permission to view or edit anything.*
