Workshop Fatal Car Crash

I have ran into a rather strange issue with the workshop. Before it became a game crasher it used to leave entire pages of Add-ons blank. After a while it froze the game and the computer forcing me to restart it every time I try to play GMOD. I’ve cleaned the GMOD files like a back ally abortionist with a Chinese vacuum cleaner, but it always seems to crash and lag my computer to shit.
