Hello,

thanks for maintaning tmuxp.

I upgraded pytest to the version in trixie-backports and it stopped
working. Even `pytest --help` breaks with a stack trace that involves
plugin loading code.

I ran it under strace and started uninstalling the packages involved in
plugins being loaded, and I got at python3-libtmux.

Doing this in a clean trixie+backporst chroot reproduces the issue:

   # apt -t stable-backports install python3-pytest
   $ pytest --help  # it works
   # apt -t stable-backports install python3-libtmux
   $ pytest --help  # it explodes

I cannot reproduce this in a current sid
