sandbox gamemode broken

[wishbone]

I wanted to test something on singleplayer when I finish loading the Q menu does not work and I get these errors

vgui.Create: Error when calling 'CreationMenu':Init ([@lua\includes\extensions\vgui_sciptedpanels.lua:166] vgui.Create: Error when calling 'PANELTABLE':Init ([@lua\includes\modules\weapons.lua:28] bad argument #1 to 'pairs' (table expected, got number))

Reinstalling Garry's Mod seems to fix this. (or renaming the Garry's Mod folder)

I tried but it didn't work.

Come to find out it was a weapon pack I got :(
