Running from the latest commit using my PKGBUILD:

Traceback (most recent call last):

    win = MainWindow()

    raise RuntimeError(
RuntimeError: Gtk couldn't be initialized. Use Gtk.init_check() if you want to handle this case.

I haven't built or run it in awhile, so I'm not sure if it's related to Python 3.10 or not.

Serval WS (serw12)
Manjaro GNOME
gtk3 3.24.31
python 3.10.1
