The solution here is to upgrade Python to the latest version like Python 3.9 where the problem has been fixed.
Another option is to downgrade Python to Python 3.6, which is a stable version of Python where the issue between Python and Django does not exist.

If you do not want to upgrade or downgrade python, you can choose to upgrade Django.
You can upgrade Django like this
