Pressing "M" solved it, Thank you!
Great! So probably what was happening is that you were launching in VR mode, even when you wanted to use it Desktop only. When opening in desktop mode, open using VaM (Desktop Mode).bat (as otherwise if you have any sort of VR headset or software active on your computer, opening VaM.exe will open by default in VR mode, with a black screen on the desktop, and the game only visible through the VR headset.
