I am attempting to add a third party application (django-music-publisher) into my existing Django Oscar 3.1 applications following the instructions here in the django music publisher documentation.
My current Oscar setup works but as soon as I add ‘music_publisher.apps.MusicPublisherConfig’ to my installed apps, I get the error:
django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.
Which is preceeded by this stack trace:
Exception in thread django-main-thread:

I have tried the suggestions on this thread: "Stackoverflow thread on a similar error with Models not loaded" as well as other similar threads. Unlike these previous questions, I am using Django 3.2. I am also using Django-oscar 3.1
Here is my wsgi.py file:
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'backend.settings')
application = get_wsgi_application()
I have no idea why it won't work... Please let me know if you need more information on my end.
