All Objects in Scene disappeared

Hi,
I don’t know if this a technical issue or not, but all of my objects appear to be invisible. I tried to reinstall Unity but it’s no use.

EDIT: Looks like creating a new scene doesn’t solve the problem…

If you are using : GameObject => Create empty, so your object will have to mesh renderer… Show us the inspector, we cant really know what is going on in that object otherwise .

Add component, Component => Mesh => Mesh Renderer, and chose your mesh .

Î only get “Can’t get same Component multiple times” and “Can’t add due a conflicting component” (my Sprites already have a Sprite Renderer) errors.
