I'm able to reproduce this issue if vmmon64 is not already running. Were you running vmmon64 before booting into Windows? This is a workaround for now.

The problem seems to stem from returning a failure back to Windows during the boot process in the case where the host side isn't ready for communication yet (i.e. kdclient has not been loaded in the vmx process). I am still looking into it.

I believe this issue is now fixed in VirtualKD-Redux 2020.4.
