Current Work Around:
dnf downgrade proton-vpn-gtk-app until you get back to 4.13.
prevent it from updating by doing sudo nano /etc/dnf/dnf.conf
adding line after Qubes End
excludepkgs=proton-vpn-gtk-app
It’s not pretty but it will give you the icon back and ensure it won’t update or keep the qubes update from bothering you. Once a workaround is completed, this will need to be undone.
