Is that for the host or for clients? Which one is getting sent to main menu? If it is the host then the name is not correct, or maybe you have a function inside the new map and it is sending the host back to main menu.
After create session use Open Level by Object Reference with ?listen as Options as a test, if with that it is working, it is because of the name.
As a note instead of Open Level I would suggest that you use ServerTravel when changing levels.
I tried using “Open level by reference” but the same thing happens, using server travel worked, but the client keeps trying to join the session infinitely, here is the log when I try to join a session:

Try to follow what you are doing once the “prematch” level starts. Go inside the level blueprint and see if maybe you added something and forgot that is switching the level. If not, go inside GameMode, PlayerController… Maybe there is something that you missed.
As for this, it doesn’t really matter from functioning standpoint. You can create it inside a Widget and players will still be able to join. It matters for you, to know where to find things, it matters for organization reason. Most tutorials online use Game Instance because that remains the same for the entirety “life” of the game.
Also, if you are not the owner of the game “Crab Game” and this is not that game, change it to 480 as that one is used for testing, and later to your Id.
You can also use these to find in your project where they are used. Right click on them Find Reference. I forgot how it was in 5.3, but in 5.5.3 you have Find reference by class member all, and it is really useful in finding stuff that way, as it is searching everywhere for them.
I managed to make it work using the server travel, Chatgpt said I needed to add “?listen” to the server travel URL, and now it is working.
About the appid, I’m using Crab Game because it is a free game so anyone can add it to the library and ignore the region check from steam, But if this really becomes a game I’ll change it.
When you are testing a game you should use 480 or your own and when you publish the game use your own id, or else you will get banned by Steam. The 480 id will not affect your testing, people from your country will still be able to join and test.
The fix wasn’t that you used server travel. ServerTravel and Open Level are ways to change the level and how it is done in the background. The plugin you are using is expecting you to use ?listen.
