Django suddenly gives me error that Apps aren't loaded yet - django

Question

I am using Django3.1. All was working fine. I pip installed a new app and tried to run makemigrations. It suddenly doesn't work anymore. I get error 'Apps are not loaded yet'. I thought it was the app. Uninstalled it. Didn't work. Deleted the virtualenv directory. Created new one and installed all apps again except the last one. It didn't work. I had installed another version of Postgres and hadn't restarted my computer since then. Restarted but didn't work. Tested by running another project to make sure it was not new Postgres issue. That worked as expected.
Commented out my url confs and installed apps in the settings.py. But still the same error.
Tried multiple SO suggestion related to this error but nothing works. Can anyone please help.
Error from console:

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'app_name', #i hope you added app_name in settings file
or
'app_name.apps.app_nameConfig' #else try this app_name is name of your app,apps is constant key word and you will get class app_nameConfig in apps.py file
]
