Certbot fails to start

[vmato]

My operating system is (include version):

FreeBSD 14.0-RELEASE-p6

I installed Certbot with (snap, OS package manager, pip, certbot-auto, etc):

pkg

I ran this command and it produced this output:

Certbot's behavior differed from what I expected because:

Expected: certbot runs normally

To me, this error looks like a major breakage of your Python setup in general and not directly related to Certbot. See e.g. https://python-list.python.narkive.com/Q6Xc4rVB/lookuperror-unknown-encoding-utf-8.
