I have the same issue. Most of the times i select window decorations, systemsettings5 dies. Maybe worth to mention, for me this happens on wayland and it seems that kcm is not adjusted yet to work on wayland (there are some scaling issues with this part of systemsettings).
Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install debug packages and attach a new backtrace.

(In reply to Martin Flöser from comment #2) > Unfortunately the backtrace is lacking debug symbols. If you are able to > reproduce please install debug packages and attach a new backtrace. Would attached bt work? Drkonqi complained about some missing debuginfo packages, but when 'install dependencies' was clicked, it didnt install anything.
Second backtrace is entirely different. AFAIK that's fixed. See plasma-framework bugs
Unfortunately the debug symbols for original backtrace are still lacking.
