Unable to connect to virt-manager spice console

Edit: ok, I apparently need to update by searx search engines…solution is here. Sorry for the noise!

Trying to use virt-manager and getting this error in the virt-manager window when starting a guest VM:

Error connecting to graphical console:
Error opening SPICE console: Typelib file for namespace 'GstBase', version '1.0' not found

I haven’t changed anything else with the virt-manager or libvirt config other than adding my user to the ‘libvirtd’ group. The VM is just a freshly created VM to boot a Fedora 39 install iso. Here’s my libvirt config:

{
  pkgs,
  ...
}:{
  virtualisation.libvirtd = {
    enable = true;
    onBoot = "ignore";
  };

  virtualisation.spiceUSBRedirection.enable = true;

  environment.systemPackages = with pkgs; [
    gst_all_1.gstreamer
    gst_all_1.gst-plugins-base
    gst_all_1.gst-plugins-good
    gst_all_1.gst-plugins-bad
    gst_all_1.gst-plugins-ugly
    spice
    spice-gtk
    spice-protocol
    spice-vdagent
    virt-manager
    virt-viewer
  ];
}

I’m unable to find any relevant info after searching other than adding the gstreamer packages (which didn’t change anything).

Any ideas? Thanks!
