Problem With Steam API

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.

okay there is i am using advanced sessions the problem was i didnt pick a gamemode but there is an addition i cannot at all to create a session with it even tho im using the correct way the session always fails with steam im gonna send

so please if you know what i did wrong let me know
