Missing main menu HUD after packaging the game

I am following along Udemy pinball tutorial, and after packaging the game the Main HUD doesn’t show, and even if i got around it by binding a key to show the HUD, it does not possess the camera after pressing the play button

Same, the spawn ball function won’t run until the play button is pressed, but the problem is you can’t click on the play button because the MainMenu widget never appears.
