Same problem here (I think). Stock Ubuntu 18.04.1 LTS gnome-shell-extension-ubuntu-dock version 0.9.1ubuntu18.04.1
The dock has disappeared overnight (pretty sure that it's not related to any updates, since auto-updates are off and /var/log/apt/history.log does not show any installs/upgrades more recent than January 14.) I still have a gray bar with the time on top and the word "Activities" in the top left corner. It shows up if I click on "Activities" or press the Windows key on the keyboard, then disappears again. Options in the "Dock" tab in Ubuntu settings (Auto-hide, Position on screen) have no effect. Unlike the original reporter, my system was rebooted about 24 hours ago. Reviewing the event journal, I see the following appear last evening: Jan 28 21:21:56 aidev-System-Product-Name gnome-shell[3405]: JS WARNING: [/usr/share/gnome-shell/extensions/[email protected]/docking.js 1778]: reference to undefined property "_workspaceIsolation" (...)
