I recently upgraded from Ubuntu 24.04 to 26.04. When I first boot Ubuntu, all is well and I see all my previous dock icons. After some time and for yet unknown reasons, all my dock icons disappear and I see only the Ubuntu circle thing on the bottom left corner (was bottom of dock list) and the icon at the very top left that lets me search for stuff. Clicking on either one of these seems to lock up the computer. I have to reboot to do anything further. After the reboot, the dock is fully restored and working .... but it will crash again at a later time.
When the dock icons are gone, Ubuntu is still functioning as long as I don't click on the circle icon, te search icon or the 'windows' keyboard key.
