Comment:
Finally found some time to finish digging into this.
The issue lies in kservice not being able to find the needed desktop files of xdg-desktop-portal-kde
`KWIN_UTILS: Could not find the desktop file for "/usr/lib/libexec/xdg-desktop-portal-kde"`, which is due to our `.desktop` files referring to `lib64` and not just `lib`.
Will take a look how to fix this issue, but I will put a fix in together with the plasma 5.24 update, hopefully this weekend, if not somewhen next week.

Until then you can just edit the `/usr/share/applications/org.freedesktop.impl.portal.desktop.kde.desktop` to point to `/usr/lib/libexec/xdg-desktop-portal-kde`
