Skins/Background Theme unviewable

[Hrdly]

Can't view skins on weapons/items from the new Christmas shift/background (been like this for a bit, it might just be me.)

I'm not sure if I'm missing textures from a certain game or something but since the beginning of the seasonal, I haven't been able
to see any of the Ultra Rare Skins/Rare ones. Some of the normal ones I can view but others I can't and are just purple and black checkerboard missing texture.
As I haven't seen anyone else talk about this issue, it seems it's just me but I wanted to bring this up just incase.
I have uninstalled and reinstalled Gmod, still same issue. thanks
