Exception running application ru.todolist.javafx.start.Main

Solved.It was necessary to register in the second controller that in the first:
it was:
fxmlLoader.setLocation(getClass().getResource("../fxml/todolistEdit.fxml"));
fxmlLoader.setResources(ResourceBundle.getBundle("ru.todolist.javafx.bundles.Locale", new Locale("ru")));
need:
fxmlLoader.setLocation(getClass().getResource("/fxml/todolistEdit.fxml"));
fxmlLoader.setResources(ResourceBundle.getBundle("TestBundle", new Locale("ru")));

Your main class extends javafx.application.Application needs to be public. Change your class as below.
package com.front.fire;
import javafx.application.Application;
import javafx.stage.Stage;
public class FrontFireMain extends Application{
#Override
public void start(Stage arg0) throws Exception {
}
}

Exception running application Main
Upon some research, I've found the error most likely resides within the calling to the FXML loader, however after trying several different fixes I have been unable to come across a solution. Am I creating the FXML object incorrectly?
Thanks

I consider to have a closer look at the NullPointerException part which is mentioned inside the stacktrace you posted. Is the path to your file correct?

I've had a similar problem in the past. Try to change:
loader.setLocation(Main.class.getResource("C:\\Users\\micha\\Documents\\eclipse-workspace\\ProgAssignment2\\src\\MainGUI.fxml"));
to:
loader.setLocation(getClass().getClassLoader().getResource("C:\\Users\\micha\\Documents\\eclipse-workspace\\ProgAssignment2\\src\\MainGUI.fxml"));

Exception running application Homework4.Homework4
I think that something is wrong with my JDK11 / JavaFX11 that does not allow me to create any more JavaFX projects because something is making each new project have this compile error. I think the error is due to the java.lang.IllegalAccessError but I have no idea how to fix it.

I am currently using the most recently updated IntelliJ Idea to code.
Side note, I am currently a Freshman in college just starting to create javafx projects, so any help/suggestions are welcome!
I tried to look at this thread for help: InvocationTargetException when running a javafx program
Unfortunately I do not have the coding knowledge to understand the suggestions that people posted in this thread.

It turns out that I did not set up IntelliJ correctly, which resulted in my InvocationTargetException. Assuming that all of your environmental variables are correct, follow these instructions to possibly fix the exception.
