Comment 0 for bug 2044014

when configuring a new wireguard connection both via nm-connection-editor and the settings app, NetworkManager crashes and restarts, with the error message "Message recipient disconnected from message bus without replying".
Currently, I'm unable to add wireguard connections at all.
Also, I have netplan.io/now 0.107-5ubuntu1~ppa3 installed to outrule https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/2039821
