Annoying tab button (+showscores) instant crash

As above. Whenever I want to view the scoreboard, be it singleplayer or multiplayer, it will crash instantly. Any help here?

Right click Gmod in Steam, go to the local files tab, click verify integrity of game cache, go away have a cup of tea as it takes a few minutes, if that didn’t work, try a re-install of Gmod.

Yeah, that’s about all that’s possible, probably the files mixing together wrong or something similar
