It's not a problem with Python but with Gaijim or one of its dependency:

--8<---------------cut here---------------start------------->8---
$ guix environment --pure --ad-hoc python -- python3 -c 'import enum;print(enum.IntFlag)'
<enum 'IntFlag'>
--8<---------------cut here---------------end--------------->8---

Summarily searching on the interwebs it seems that python-enum34 may be
at cause.  You should look if it's being propagated by any of the
dependencies of gajim or gajim-omemo, and probably get rid of those as
this package exists for backward compatibility for Python versions older
than our 3.8.2 on master.
