I think KRunner (Alt-F2) should still work.

Looks like plasma-desktop froze. Does top show this process with 100% CPU
usage? This happened to me often.

Try this in your Konsole in order to quit plasma and restart it:

  kquitapp plasma-desktop; plasma-desktop

If kquitapp does not work, try killall -9 plasma-desktop instead. If it
hangs again, maybe you see some output in the Konsole that helps to see
what the problem is.

Good luck,
