Mailman web stopped working

After a lengthy power failure I had to reboot a machine that has been running for several years. the WEB-UI does not seem to be able to see mailman-core. I have looked for log entries that might explain what the issue is and I am stumped to even find logs that will update when I get an error on the browser. Mailman is definitely running, postgres is running and mailman web is running. if I go to the lists page I see lists, if I try to access a specific list I get Server error: An error occurred while processing your request.

I looked in /var/logs/mailman /opt/mailman/web/mailmanweb

All I can find is:

 django.urls.exceptions.NoReverseMatch: Reverse for 'list_unsubscription_requests' not found. 'list_unsubscription_requests' is not a valid view function or pattern name.
16688 ERROR 2023-09-12 13:56:58,430 1760 django.request Internal Server Error: /mailman3/lists/goodstein.goodstein.org/

  File "/opt/mailman/venv/lib64/python3.8/site-packages/haystack/admin.py", line 8, in <module>

ImportError: cannot import name 'ungettext' from 'django.utils.translation' (/opt/mailman/venv/lib64/python3.8/site-packages/django/utils/translation/__init__.py)

Also I have to run mailman from "mailman start" because the systemctl returns this:

Please tell me where to start looking or adjusting.
