Hi 

I use also Kubuntu 24.04 here and the problem is not reproducible at all.

1/ Please try with last 8.5.0 appimage.
2/ run digikam in gdb and capture the backtrace : https://www.digikam.org/contribute/#linux-host-1

The crashes between digiKam 8.0.0 to about 8.2.0 were related to the SSE detection at compile time and runtime for the QtAVPlayer.

After apt autoremove and downloading the appimage for Qt5 digikam starts normally. I overlooked the small print on the download page and clicked the first link. Thanks for the pointers.
