Sonicwall VPN Connection

Sophos Endpoint Intercept X
Since we updated to macOS Monterey 12.0 no VPN connection can be established with Sonicwall VPN (SonicWall Mobile Connect).

The client asks for the password and then the connection immediately goes to Disconnected.

If Sophos is uninstalled the connection works.
Does anyone know this behavior?
