-- Information about the crash:
- What I was doing when the application crashed:
I just closed microsoft visual studio code and then my mouse and keyboard stopped working. I could move my mouse or press a key on the keyboard, but nothing happened. After a moment the task bar disappeared and came back. After that I could work again.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
