I have a cleanly installed Windows 11 Multiplicity KVM Pro Host and I'm connecting to a headless Windows 10 21H1 but all I get is a black screen. If I have the sidebar open I can see the remote's desktop, or lock screen, in the thumbnail but when I click connect I just get a black screen.
I have tried every setting combination I can think of. I have disabled my anti-virus (Sophos Home). I have removed other remote agents, like GoToAssist and nothing works.
Any suggestions are appreciated.
