Broken TTT Traitor Menu

Whenever I open the context menu, it shows a gray box with only icons and it says this,

[ERROR] lua/vgui/dimage.lua:153: attempt to index local 'Mat' (a nil value)
  1. FixVertexLitMaterial - lua/vgui/dimage.lua:153
   2. SetImage - lua/vgui/dimage.lua:131
    3. SetIcon - gamemodes/terrortown/gamemode/vgui/simpleicon.lua:69
     4. unknown - gamemodes/terrortown/gamemode/cl_equip.lua:267
      5. unknown - lua/includes/modules/concommand.lua:69

I really need help. :frowning: Thanks

I added a picture, someone please help! :C

Mat is nil

we really don’t have enough information to help

It was fine yesterday, That’s all it gave me, I’ll see if deleting some addons help.
