Shaded Viewport and Render issues

I feel like it has to do with viewport properties, or something. It was working fine last night I don’t know what happened or what I did differently today. In Render mode the environment doesn’t show up, the ground plane seems corrupt and the metal looks like a flat dull color. In shaded mode my objects are grey no matter what layer its on, please help!.

Hello - please reset the display modes to defaults in Options > View > Display modes. Does that sort it out?
