I just started "git gui", when the notebook froze for a few seconds. Afterwards, I could access most running applications, but chrome only rendered the tab bar, and plasmashell would not start again.
I had only just updated the KDE libraries from 5.44.0 to 5.45.0 when this happened. Not sure if this is related.
