I can reproduce this issue, too.
When plug in the dock(with HDMI 4k monitor), the screen freeze and keyboard/touchpad won't work, but I still can ssh into the machine.
Un-plug the dock, everything works again.

BTW, I found gnome-shell runs in 100% while the issue happened, and un-plug the dock the CPU usage of gnome-shell comes back to normal.
