Nope. Based on a udemy class I’m taking, you need to create a new Game Mode. Your game is starting at your level instead of the main menu because the default game mode is set to the one that your level uses. (and your main menu doesn’t override that)
So, create a new Game Mode: Right click in some appropriate folder, new blueprint class, game mode base, call it something like GM_Main_Menu. Save All.
Back in your main menu level, next to the Details panel click on the World Settings tab. (If the World Settings tab is not visible, make it visible by going to Window, in the Level Editor section: click on World Settings.)
In the World Settings tab, find Game Mode, set Game Mode Override to the game mode we just created earlier.
You might also have to go into Project Settings, Project, Maps and Modes, and set the Default GameMode to your MainMenu one. And maybe muck with the Default Maps as well.
This was in UE 5.1 for me, hopefully other engine versions are similar enough. As usual with Unreal, it’s obscure and impossible to figure out until it’s “just click here, there and enable that but disable those” obvious.
This is the way. (I think… I’m still kinda noobish)
