I have a similar issue. I have set up the Windows 11 VM. The initial Windows VM installation starts and every time it reboots the screen goes blank in the noVNC window. I'm past the initial setup installation, this happen when the windows installer runs. If I forcestop/start the VM, the display is back on, but the windows install starts from scratch. What am I doing wrong?
I've shared VM setting screenshot. Any help is much appreciated.
