Strongswan - Unable to load VPN connection editor)

Hi guys, I have a problem with strongswan VPN.

When I connect via IKEv2 I don’t have username, password, address fields. It gives the following error (Error: Unable to load VPN connection editor). I managed to add VPN via nm-connection-editor, but when connecting it gives the following error Activation Network Connection failed

System - Manjaro GNOME.

Maybe someone has encountered this error?
Thanks.

Maybe the following will be helpful?
