Player Model Glitch

I am currently having a problem with player models in my game which make them look like this :

I have tried verifying my files and am currently re installing my game. I have no idea what is causing this.
Thanks for any help,

Edit: I should also not other people do not have this problem on the same server.

Have you tried it on another server? Or deleted all the addons?

I just reinstalled and had the same problem, tried other servers and I didn’t have the problem. Currently removing addons from my server till I find what it is.

I’m an idiot it was a faulty detective addon. Thanks for the help anyway!
