Couple of issues, GMOD closing to desktop when opening Console

[StalkerUKCG]

So Haven't used GMod in forever.

Fresh download, Only downloaded files are Dead Island Hexed survivors from the workshop (which spawn invisible, Any help on this would be appreciated)

L4D1 and L4D2 survivor models are loading missing textures, Seems to be a LOD issue since when I get further away the textures appear.

GMod will Crash/Close (No error message) to desktop when I try to open the dev console.

Go to your Garry's Mod root folder; do you see any .mdmp files?
