This is because launch(args); is a "predefined" JavaFX method, located in an abstract class.

Take a look at the following:
As you can see, the method only accepts one argument.

public static void launch(String... var0) {
      // Heres the logic
}

To Fix that, you could do the following:

1. Declare your Map<String, String> outside of your main()
2. Only initialize it in your main method
3. Access it via this.userInformation in your start-method
   To visualize everything, heres some code

public class Gui {

   private static Map<String, String> userInformation;

   public static void main(String[] args) {
      
      // All the other logic
      userIformation = scanDocument(file);
      launch(args);
   }

   public static void start(Stage primaryStage) {
      
      // All the other logic
      // Here you can access your Map<> by
      // simply using userInformation.blablabla();
   
}

I hope this helped you a at least a little bit.

And also... Please never use german words or none of the english letters (like öäü) in variablenames...
