After selecting "Display and monitor" in the left pane, the next pane change causes a crash. Navigating to another item in the left drawer (e.g. "Input devices") also crashes, albeit in QQuickWindow::maybeUpdate, rather than QQuickWindowPrivate::dirtyItem. A workaround (and possible hint to narrow down the cause) is to enter "compositor" as a search them, which filters the left pane down to "Display and monitor" and clicking on that, which directly shows the compositor pane successfully. After removing the search term, navigating away also works without a crash. (So the issue seems to be more about pane navigation than the Compositor/Night Light windows themselves?). HTH

HTH Good catch. Workaround confirmed, here. Similarly, once that pane is narrowed from everything else the rest of the Display tree can be navigated as well.
I am experiencing the same problem. Workaround works. This happens even in 5.17.1. Under new user the menu items accessible again, but after a while of setting up the new account the bug returns. I didn't catch what tripped it. So the config files seem to have an influence.
Workaround works for me to,also alternative solution would be to switch to icon view and access compositor settings to avoid crash.I can confirm that crash can be reproduced in 5.17.1
Arch has pushed KDE Plasma 5.17.2 and systemsettings 5.17.2 to stable...Crash still occurs, workaround still works.
I think issue might be partially solved,because since update to 5.17.2 crash occurs only on my work machine,it can't be reproduced on my home installation.

Potentially fixed by aea58fcca35984fff73e1c77dc2edb346da4e69b in kcmutils which will be in frameworks release at the start of November. Could someone who can reproduce the crash please confirm.
It is fixed for me. I can't reproduce crash anymore.
Cool, please reopen if it's still an issue with the upcoming frameworks.
