Ubuntu Dock (dash-to-dock) broke on upgrade to Gnome Shell v45.2 about dash-to-dock HOT 3 CLOSED

I would try uninstalling and reinstalling the dock, but I have done this in the past and had problems.
This could be an Ubuntu issue, but I have a feeling that the dash-to-dock extension may need checking for compatibility with gnome 45.2.
The dock showed as disabled on reboot after the update. Enabling had no effect.

I rebooted and the dock was not present and was marked as disabled again.

Apologies.
I disabled all my other extensions and the dock reappeared. I re-enabled them one at a time and discovered the problem.
I had dash-to-panel installed, which is known to clash with dash-to-dock, so I removed it and have no more issues.
