I\'m a noob trying to learn Django for the first time, I created a project in a virtualenv on Windows 10. It worked well in the beginning where I was able to login to the admin
It's a Django 3.0 issue as I've seen. There are so many issues on GitHub, regarding this error.
You may try downgrading to Django 2.* versions for now. Version 2.1/2.2 works fine.
