What version of Django is installed? 4.1.2
If your main priority is to get mailman-web working, I suggest trying a downgrade of Django to 3.2.x. (Probably x=16 is current but any x in double digits should be OK).
We just a couple weeks ago merged patches from a 3rd party to support Django 4. So quite a bit of risk here, I don't think any of the core devs are running Django 4 systems yet, and I know none of the production systems at python.org and mailman3.org do yet.
If you're willing to help us get our code in shape for Django 4, of course we'd love to have a beta tester. :-) But to be honest, I have no idea what's going on with that error, and I don't know if either Abhilash or Mark would either. So it may take a while (or Mark could pop up in 10 minutes and wave his magic wand and all will be well -- that's life in the beta lane ;-).
