libvirt's udev interface backend (RHEL 9 and later, Debian 12) only reads interfaces, so the create form and the start, stop and delete buttons only failed there. The pages ask the host with an invalid definition, which defines nothing: a backend without define refuses it as not supported. There they show the interface state and a note instead, and posts change nothing; the host's devices, needed only by the create form, are not read. Any other answer keeps the pages as they were.
