This is a community request for help. Can anyone solve the black screen problem when dom0 uses IGPU and RTX4090 installs pass-through to any appvm?

I found that the information in the official documents was a bit outdated and could not solve my problem, so I came here to ask for help. I also posted in the community. Please help me. I will be very grateful for your help.
