Just found this bug report: https://bugs.kde.org/show_bug.cgi?id=481979 indicating the same issue with "KDE NEON" In the first comment (from "Patrick Silva") it is suggested this is due to a packaging issue.
https://build.opensuse.org/request/show/1158213 + https://build.opensuse.org/request/show/1158212 you can install phonon-vlc-qt6 manually to fix your issue

Looking at an older (20240303) TW install on another machine it appears to be using "phonon4qt5-backend-gstreamer" - is there not a qt6 variant of that? as I don't really want vlc installed.

(In reply to Christophe Marin from comment #4) > (In reply to Paul Tannington from comment #3) > > no, the gstreamer backend is gone. Ah! OK. That is, though, rather unfortunate. So, dolphin now in effect, depends upon vlc if one wants audio/video in the preview panel.

See https://bugzilla.suse.com/show_bug.cgi?id=1219416 on the same topic. vlc itself isn't used, but we need the plugins provided by the package.
