Since recently, I have the same issue, didn’t had time to investigate.
check if the following thing help you:
Try to remove this line from the policy
admin.vm.property.GetAll * sys-audio @tag:audiovm-sys-audio deny notify=no
and from /usr/lib/python3.12/site-packages/qubesadmin/tools/qvm_start_daemon.py
modify the line
from
events = qubesadmin.events.EventsDispatcher(args.app)
to
events = qubesadmin.events.EventsDispatcher(args.app, enable_cache=False)
