I am using the newest one available which at the moment is Magick.NET 7.0.0.0102.
Prior I used version '7.0.0.0022' but due to some strange problems with TIFF images I switched to '7.0.0.0101' and yesterday because of the psd problem I updated again.
Using your provided code generates two defective psd files. When I switch width and heigth I see the expected red images. You do not need to know or even have Photoshop. Just generate the psd files and use FastStones MaxView image viewer (portable, windows only) to open them. MaxView does not show fancy error messages like PS does, but the images are clearly broken.
