Error in snap installation

[Gaiden]

hi!
I’d like to try bluemail in my new opensuse installation but flatpak doesn’t work (first launch: nothing clickable); so the Bluemail team recommend to install from snap.
I follow this guide: Snap - openSUSE Wiki
but when I try to

sudo systemctl enable --now snapd

i got this error: Job for snapd.service failed because the control process exited with error code.
See “systemctl status snapd.service” and “journalctl -xeu snapd.service” for details.

and if I take a look at, there’s the message:

systemctl status snapd.service
× snapd.service - Snap Daemon
     Loaded: loaded (/usr/lib/systemd/system/snapd.service; enabled; preset: disabled)

TriggeredBy: × snapd.socket
   Main PID: 3677 (code=exited, status=1/FAILURE)

could you help me please?
