Django Project - Update made inadvertently now failing

I am working on a Django Project 3.0.7 using Python 3.8. Something was updated inadvertently [like the title says] and I can't seem to figure out what it is.

Any assistance is appreciated, full traceback below:

You have either updated your Django version or the database backend. You can roll back to a previous working state if you are using VCS and try reinstalling the libraries (I hope you had specified the versions in requirements.txt).

The traceback

  File "C:\Program Files (x86)\Python383-32\lib\site-packages\django\db\utils.py", line 207, in __getitem__
    backend = load_backend(db['ENGINE'])
  File "C:\Program Files (x86)\Python383-32\lib\site-packages\django\db\utils.py", line 111, in load_backend
    return import_module('%s.base' % backend_name)
  File "C:\Program Files (x86)\Python383-32\lib\importlib\__init__.py", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "C:\Program Files (x86)\Python383-32\lib\site-packages\sql_server\pyodbc\base.py", line 12, in <module>
    raise ImproperlyConfigured("Django %d.%d.%d is not supported." % VERSION[:3])

points to that you may have DATABASE_ENGINE='sql_server.pyodbc' which is supported via django-pyodbc-azure. Why? A quick GitHub search led me to the line 12 of django-pyodbc-azure/sql_server/pyodbc/base.py which is in sync with the traceback path. If you are indeed using that library, it looks like it works with Django 2.1 only. Are you sure you weren't using Django 2.1 when it last worked? Or maybe you installed this library after installing Django 3.x and it is correctly throwing an error in which case you should look for a different library for your database backend that supports Django 3.x or downgrade your existing version to 2.1.
