FragsAreUs In the end the port works, thank you very much

I'll try later but I have a doubt, I wanted to host a normal game, not a dedicated server

Hi, recently a friend of mine downloaded bo2 plutonium and we decided to play, I opened ports 4976 and 4977 on my router but it still can't connect, I'm not going to enable upnp because it's insecure, can someone give me some Advice? I've tried both multiplayer and zombies

Resxt I still have the error

Hi, when I try I press play on the launcher and start the zombie mode (it does not happen on multiplayer) the game opens for a few seconds but then immediately closes, I attach the screenshots of the error and of the game folder.
I don't know how to fix so I ask for help, thanks in advance.
