So I packaged my game, and when I try to play it looks like this :
I think we need some more information about this.
All i can come up with is that you are not using the first (main) level that you’ve created or you messed up the preferences for the world, editor, level, or you are not using a player, gamemode, player controller, etc.
The game works when I play it in the editor
It also doesn’t work when I play with launcher
