One more thing, I sent a report to Daniel Mendler and we found out that
the issue is that minibuffer-allow-text-properties was set to t by
something. He also wrote this:

"While I insist that it is a mistake to set minibuffer-allow-text-properties globally, I still wonder why Gnus uses propertized
candidates in the first place, in particular with a useless fontified=nil property. Ideally commands which pass propertized
candidates can also handle propertized return values. So maybe a guard could be added to Gnus, but I would rather
recommend to strip the properties properly before passing the candidates like text/plain to gnus-completing-read."
