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:

(I think the dock was still up after 21:22, but I'm not positive.)
There are lots of other recurrent Gnome-related errors in the log, which
may or may not be related. These include:

Title:
Ubuntu Dock gets replaced with a standard GNOME one after a while
Status in gnome-shell-extension-ubuntu-dock package in Ubuntu:
Confirmed
Bug description:
I don't reboot my desktop and don't hibernate it, it just works for
multiple days in a row without a reboot. I only turn off the monitor
when I go out.
Sometimes, after a while, when I turn on the monitor, Ubuntu's Dock is
no longer there and what I get is the GNOME Dock which is hidden and
can be seen by pressing "Super" (which shows all windows as well).
This is annoying.
Not sure if related, but here's what I've found in the journalctl
