Now, with kwin-wayland 4:6.5.0-1 in testing, I don't have the crashes anymore.
Closing as fixed in that version.

Dear Maintainer,
* What led up to the situation? three-monitors setup: laptop + 2 screens
connected to a USB-C (non-thunderbolt) dock
* What exactly did you do (or not do) that was effective (or
ineffective)? disconnect the dock
* What was the outcome of this action? All displayed app crash.
* What outcome did you expect instead? Windows should get respositioned on
the laptop screen.
