I am running Mint Linux.

I tried to allow everything in /usr/share/dbus-1/system.d/org.freedesktop.NetworkManager.conf without any success. Same error occur.

i think your problem is polkit permission.

Since you are using NetworkManager, this solution from the Arch Wiki may help: https://wiki.archlinux.org/title/ProtonVPN#Official_client_will_not_connect

In short, on Arch Linux, install network-manager-applet. On Mint, I couldn't find the package, it may be included in the main NetworkManager one.
In any case, run nohup nm-applet > /dev/null & to launch the applet. Restart the ProtonVPN app for good measure and try to reconnect.
