All of my scenes have become blank. The objects are still shown in game mode, but not in the scene view, which appears to be empty. When I double-click an object, it shows me the mesh of it, but when I deselect it, it disappears again. What should I do?
Try to change your viewmode in Perspective and check your Quality Settings ( edit>projectsettings> Quality). Or maybe your Polycount is to high ( look at your console, in this case you should see an error message with “> 60000 polycount” or s.th.)
Make sure all layers are set active.
