I'm trying to create application using FXML file for my window, but I can't get this to work, none of answers on StackOverflow worked for me and I'M stuck.

Class where I want to load file

public FXMLWindow() {
        final FXMLLoader fxmlLoader = new FXMLLoader(this.getClass().getResource("/test.fxml"));
        fxmlLoader.setRoot(this);
        fxmlLoader.setController(this);
    try {
        fxmlLoader.load();
    } catch (IOException exception) {
        throw new RuntimeException(exception);
    }
}

FXML file

<AnchorPane prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/17" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.FXMLWindow">

and errors
