So my problem is when i go to listen server it returns me to the main menu now im not sure what causes it but i tried everything on how to travel with multiplayer on and all that and it hasnt been helpful
It’s a known bug, present since 4.26
Use a plugin called Advanced Sessions to create/find/join a Steam lobby
Also, check in project settings > packaging if all relevant maps are added in List of maps to include in a packaged build.
