This happened to me recently, from one day to another, because the game worked very well since first day, i don’t know what happened :'c when i make a server, my frinds cannot join :'c

Thank you!, sry my bad english, hope you understand it! c:

It looks like one of the addons or workshop items isn’t installed properly, it’s trying to use console commands that should exist but don’t
