do not have a dock after unlocking from lockscreen

[Dennis Westerbeck]

When I lock the screen and unlock it again after a while, my dock has no application icons anymore. Just the 'show applications' button is still present. If I click that button I get to the applications menu but without any icons etc. just gray and cannot press anything nor come out of that screen. (sometimes there are some not-clickable application icons displayed) The apps still opened on the screen work perfectly fine (as far as I tried).

My system:
I have an Ideapad 5 Pro with AMD Ryzen and Radeon
Ubuntu 22.04 (installed a couple days before)
Most time with 2nd screen: Dell UltraSharp 27'

I sometimes had the same issues in ubuntu 20.04 before I upgraded (but they did not occur regularly)
