I installed content and this addon. It all worked fine but after i clicked Half life weapon it crashes the game. But if I join Meta Construct and this crowbar changed the skin itself:

But on my own server it look liked this:
https://steamcommunity.com/sharedfiles/filedetails/?id=1576880261 (With chrome on my server)
Now i can't equip HL1 weapons on my server because of the crash. Please give me the info about this issue.
