No menu no sound no player models?

When i launch Gmod it loads the game (the facepunch studios screen) but after that all that is shown is a Blue screen. when i join a friend via steam, in game theres no sound at all, and no player models. I assume the player models cna be attributed to me not being able to add the extensions (CSS HL2 TF2 ect. ) but i cant figure it out.

Here is my console when i launch the game

Verify your game cache.

I did, twice any other solutions? I havent played gmod in months and i dont know what could have messed it up?

Delete your garrysmod folder, the one located at (steamapps/[username]/garrysmod/) unsubscribe to any addons you may be subscribed to before you do so via the Steam workshop, verify the game cache again, and uninstall and then reinstall garry’s mod. If that doesn’t fix it, there’s no fix.

how do i unsub from addons? havent played since before steam workshop was first created.

So chances are you have none, just uninstall and reinstall.
