So... How about a fix!
For Ubuntu 18.04.3 the bug happens when you inadvertently hit the gnome-control-center devices/thunderbolt section.
gnome-control-center segfaults and will not restart! Fault:
(gnome-control-center:8315): thunderbolt-cc-panel-WARNING **: 15:36:34.212: Could not create client: Error calling StartServiceByName for org.freedesktop.bolt: GDBus.Error:org.freedesktop.systemd1.UnitMasked: Unit bolt.service is masked.

Instead of waiting for a fix to this that happens upstream from Ubuntu18.04.3 you can just:
sudo systemctl unmask bolt.service
sudo systemctl stop bolt.service
sudo systemctl start bolt.service

The stop probably isn't necessary, but it doesn't hurt!
