Host game not working with Steam Appid / Unreal 5.3.2

Hi, I have created a game with online and I can host game and another player can find it. The problem I have is that after compiling when I add the AppID and run the game with steam when I hit host it takes me to the online lobby map for a moment but then returns me to the main menu. This only happens when I add the AppId either 480 or whatever. When I put the -log it only tells me the following:

If i play in the standalone version in the engine it wont work either and this is the log:

When i remove the listen option from the openlevel node it seams to work but then it doesnt work online:

Please help me I have the game ready and published the page on Steam but now I have encountered this error which is only happening to me with this project. I am using Unreal 5.3.2

I managed to solve it by adding this lines to the defaultengine.ini

[/Script/Engine.GameEngine]
!NetDriverDefinitions=ClearArray
+NetDriverDefinitions=(DefName=“GameNetDriver”,DriverClassName=“/Script/SteamSockets.SteamSocketsNetDriver”,DriverClassNameFallback=“/Script/SteamSockets.SteamNetSocketsNetDriver”)
