Invisible player and tool gun malfunction

Um, hi. Well I noticed that whenever I use a swep that puts my hands to my side, or when I enter a vehicle, I’m invisible. Yet it fixes when i type “chasecam” into the console and then jump. It never happened before, so I was wondering what’s up? Then I noticed none of the features of the tool gun work anymore unless I aim it at a prop. This started happening right after I downloaded the Mario Hat, yet it still continues after uninstalling it. Anyone know what’s going on and how to fix it?

Try cleaning up your Gmod folder.
