I think restarting mailman core can help.

The output of pip freeze|grep falcon is: falcon==1.4.1

Also, on opening http://127.0.0.1:8001/3.1/,

A server error occurred. Please contact the administrator.

This is what I got and terminal showed address already in use error.

Check the falcon version again. Also restart the mailman core. What is the error that you are getting when you open http://localhost:8001/3.1

This is the part of settings.py.

Output of bin/mailman conf:

Also, as suggested by Krishna, I installed falcon but nothing changed. Btw, Thanks for the help.
