Blank screen in some apps

My pc was turned off forcely, since the whole system was freezed when I was debugging some app in vscode(the reason may be the whole ram had been occupied).
Now, after boot, I have black screen with mouse cursor, but I was able to run gui apps from cmd(opening cmd with ctrl+alt+t).
I solved black screen problem by removing ‘~/.local/share/kactivitymanagerd/resources’ folder with its content.
There is another issues where some gui apps not showing its content - they show ‘blank page’ instead.
For example, I have sublime text, putty - they do not show its content, after opening.

Elisa also cannot be lanuched anymore.
This is the log when from cmd:

reinstalling these apps didn’t help

I cannot add to ‘favorites’ any apps.


What may be a problem? What packages/settings should I reinstall/remove(reset) ?

I don’t know how to resolve the error but this is something you should never do. Check if your disto has REISUB setup if not set it up. This can solve many headaches.
