-- Information about the crash:
100% of the time, when selecting any category on the sidebar of the System Settings application, it crashes. This has started happening a few weeks ago with a system software update from the official Fedora repos. I did not alter any settings regarding this application, it just started crashing like this. It will also crash if the program is exited out by clicking the close window button in the title bar.

I have NO IDEA why this is happening. I have sent countless automatic crash reports for this via the Crash Handler application, but nothing has been fixed. I know the Fedora developers have been busy with Fedora 43, and there have been conventions that have taken up people's time, but crashes like this should be setting off alarms if crash reports actually do get delivered to the developers.

The crash can be reproduced every time.

Oh, I didn't know about those bug reports, nor the KDE Discuss thread which has an actual solution, which was to run `sudo dnf swap kf6-kirigami-oxygen kf6-kirigami --refresh` and things now work correctly. Sorry about that!
