wireguard, nmcli - Connection activation failed

hello all, I recently tried to activate a mullvad vpn connection using wireguard
I installed the wireguard-tools and wireguard-lts module since I'm using the lts kernel.
After following all the steps for activating the connection that are shown on the wiki:
the connection fails after issuing the last command

nmcli connection up connection_name
Error: Connection activation failed: mlvd failed to create resources: Failed to create WireGuard interface 'mlvd' for 'mlvd': Operation not supported

Re: wireguard, nmcli - Connection activation failed

You probably updated your kernel without rebooting.
