Attaching stacktrace from forced SIGSEGV SOFTWARE/OS VERSIONS Operating System: Kubuntu 21.04 KDE Plasma Version: 5.21.90 KDE Frameworks Version: 5.82.0 Qt Version: 5.15.2 Kernel Version: 5.11.0-17-lowlatency (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i5-8250U CPU @ 1.60GHz Memory: 7,6 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620

The crash log only tells us that KWin crashed; sadly it's a known and unavoidable issue that when kwin_wayland crashes, all apps crash too (see https://bugreports.qt.io/browse/QTBUG-85631). The app crash logs are not useful; all they do is tell us that KWin crashed. But we need to know why KWin crashed. For that, we need a backtrace of the KWin crash itself. You may be able to retrieve it with `coredumpctl`. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl
My memory betrays me, but judging from the plain stupid comment i made ("Attaching stacktrace from forced SIGSEGV") i guess i manually send signal 11 using htop to the process and that should be why it crashed. If this is the case it might be because it had high CPU usage after login, but i don't remember if that was the case or if it was really a crash unprovoked by me. I doubt it judging by the comment.
Just installed systemd-coredump over apport. It shows many crashes, all of which "missing" corefiles. It seems this bug would be a no-op. That said can apport be used for invoking gdb (and if so updating KDE documentation) instead of coredumpctl, as apport would report to Canonical in case of Ubuntu crash. Looks like conflict of interest for bug info between KDE and Canonical.
Sorry for the spam, just fount out one can apport-unpack the crash report and gdb the coredump afterwards. I suggest including such apport instructions here: https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl
