Error: Monitor is disconnected

I’m getting this error when I try to start vm with vga.
Been using it for a month now, now this.

If the host has recently upgrade to LXD 5.0.1 you may need to restart the VM, see LXD 5.0.1 has been released

In my case I restarted the VM but still didn’t work. Rolling back to a snapshot did the trick.
