Completely White Canvas / Stage

I created a simple animation for our menus. This was a recent project. Last week. I need to make some edits and when opening the entire stage is white. The layers, assets, timeline all fine. I can edit. I just can't see what I'm editing. I've updated, unistalled and reinstalled. This even happens when I try and just create a new project. Please help. NOice in the image I am zoomed out to 16% Its all white.
