Virtio Windows 11

I have a KVM host on Rocky 9.3, I have build a Windows machine 11 that I installed successfully with Virtio Drivers.I amde several restarts the first days and it worked.
Now when I came back checkking it I see that Newotk Doesnt work anymore even if I restart…
So Redhat VirtIO Network Card does not work.
What might be the reason?
Server is fully updated…
thank you
