Looks ok.

Please run pacman -Qk bash

Also good to see if you have anything installed from AUR: pacman -Qm

Hm, I don’t see anything strange here.

You could uninsall python-pulsectl and see if the fixes it. But I doubt that this would help.

I guess you have installed

gobject-introspection
gobject-introspection-runtime
47

It doesn’t change anything right after installing it…
And reconnecting ofc
