Issue with Debian 12 KDE and Custom VPN

Hi all, I am unable to make a custom VPN connection through my Debian 12 KDE system. After that I added the protonvpn guide, I can’t automatically connect to it through the network panel in KDE. That is, I have to enter the password for the protonvpn account every time, and then the vpn works. When I fill in all the data for automatic login, it gives me an error and I have to enter the password again.

Also, after that, I enter the password in the vpn settings, and after closing the settings, the password disappears

How to fix that?
