Anything I import or add to the composition just doesn't show up. I'm constantly looking at a void.

What does work though is playing/previewing the animation. But the second I stop the preview it goes blank again and I can’t edit anything. When I mean anything I mean everything I try to import. I’ve tried editing a plethora of Preference settings, Image settings, trying new images to import, image settings, composition settings, I’ve tried downgrading my AE, I’ve also tried downgrading and switching my drivers to studio drivers but nothing changes.
