Mailman3 got broken by the update to Python 3.13.
We are working on a fix, but it looks like fixing something results in replacing it with a new error ;-)
Mailman stack was downgraded to Python 3.12 and the service is online again for the time being (temporary setup, implementation of a proper solution is still pending).
