Failed system checks when hosting application

When I try to host my web app, I get this:

(workout) sahands-mbp:workout sahandzarrinkoub$ python manage.py runserver
Performing system checks...

Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x10ce3b950>

I can't interpret this error message, because it doesn't look like a normal python error message. Before I got this error, I was experimenting with dropping sql tables from the application, and also with customising the default Django User model. Could this be a cause for the error? And how do I solve it?

Update:

I had this code in my models.py:

class User(AbstractUser):
    pass

When I removed it, the error disappeared. I don't know why.

Did you follow these steps from the docs?

Don’t forget to point AUTH_USER_MODEL to it. Do this before creating any migrations or running manage.py migrate for the first time.

Also, register the model in the app’s admin.py:

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from .models import User

admin.site.register(User, UserAdmin)
