Have been able to recreate this issue for quite awhile now on both stable and git kde/qt packages, on two systems and distros. However, all that's needed for me is to power off a monitor. Worth noting that if auto login is enabled, kwin will continually try to start and crash, using quite a bit of power.
Is it still an issue in 5.26 or 5.27?
