Qubes desktop not reacting

Hi, after restarting well functioning Qubes the desktop doesn’t react properly.

(management template is fedora-43-xfce)

  • The Q in the upper left corner doesn’t react.
  • in the panel there are no icons like network, disk, usb connections or dom0 clipboard. There are icons of audio, user and battery.

Right click on desktop gives the normal menu, I can see the content as usual but cannot run anything except for dom0. But no qube-manager or global config can be started.

qvm-run [appVM] and qvm-remove [appVM] don’t work
.
With the help of AI:

sudo lvs -a.

  • none of the LData% or Meta% is close to 100%

sudo journalctl -u qubesd -n 40 --no-pager

  • qubes.exc.QubesValueError: Invalid length of interfaces=‘None’ (is 4, expected multiple of 7)
  • Failed to start qubesd.service - Qubes OS daemon

sudo systemctl restart qubesd

  • Job for qubesd.service failed because the control process exited with error code.

Seems like the /var/lib/qubes/qubes.xml is damaged?

Run out of ideas. Any idea how to solve this?
