CodePudding user response：

The problem is not from your code it's from django_messages package that you installed

File "C:\Users\Christopher\AppData\Local\Programs\Python\Python38\lib\site-packages\django_messages\apps.py", line 2

You can fix this bug manually by overriding the package but the bug gets back every time you install the package again (in another environment)

My suggestion is that create a new issue for django_messages or try to fix the bug and merge request it.
or use django 2.2 as the author of the package mentioned in the README of the package.
or use another package ...

CodePudding user response：

This is not related to your project but django it self because ugettext_lazy has been removed in Django 4.0 . Just use gettext_lazy instead .

possible solution :

in django-messages open field.py in line 8 change :

from django.utils.translation import ugettext_lazy as _

to : from django.utils.translation import gettext_lazy as _
