Fedora KDE desktop GUI [plasmashell] crashes

Desktop often crashes after waking up from suspended state.

What works:
Alt+Tab
Ctrl+Alt+Del
Applications

Questions:

  1. Is that possible to add in Ctrl+Alt+Del menu option to run terminal command, I could add fix below to repair.
  2. How to fix?

PS: my temporary fix is:
Open terminal [Ctrl+Alt+T]

kquitapp6 plasmashell
kstart plasmashell

And it works without logging out.
