I've read every forum and workaround for getting multiplayer to work, but regardless of what I do I can't join lobbies or even host one. Every other multiplayer game I own works as intended so I know it can't be an internet issue.
Just to preface, I have purchased the game on pc, both through Steam and the Microsoft store to be safe.
I've tried: Turning off my firewall entirely, turning off my anti-virus entirely, opening all ports, using a vpn, fresh installing the game multiple times, restarting my pc, spamming host/join game and trying all of the aforementioned methods through 2 separate accounts.
There is absolutely nothing I can do and it's extremely discouraging because I am the only one in a group of 5 friends who is having an issue.
