Ich weis es ist viel code aber ich weis nicht wie ich es sonst machen sollte...
wenn man die 3 klassen einfügt sollte es funktionieren und Sie könnten es selber ausprobieren
das aktuelle problem ist in der Klasse DeckStackPane der Action Handler
für das Menu Objekt returnToMainMenu
es führt den action EventHandler aus und geht dann in die GuiFunctionsForAll rein
und führt dann setTheMainScene aus das ist auch noch erfolgreich
und DANN kommt die Exception
Bestimmt kommt das Kommentar dass der Code furchtbar ist xDDDD
