Work area grey and can't see page elements. Help!

I’ve just reopened a document I was working on a few weeks ago to complete a few final amends.

The scenes/layouts to the left of the page are visible but the main work area is blank and the same grey as the UI (see attached screen). I can still select elements and see their bounding boxes (but not the element visually), I can also still preview the site in browser locally.

Is this a known issue? This site is due to be published live tomorrow. Speedy help would be greatly appreciated.

cheers
