Model becomes blank grey outline in Material Preview and Render Preview modes(also when rendered)

I came back to a project after a few weeks to find that when looking at the material preview and rendering preview, the object would only appear as a grey shape(all texture vanished. I sent the file to a friend who was able to see the model correctly. I tried updating Blender and my PC’s gpu drivers with no luck. Is this just some setting that I missclicked or a hotkey I hit because I am really stumped.
