I have a JavaFX app with multiple FXML files and controller classes, it uses both MySQL and HSQL, I am trying to run this app in order to edit it but when it runs, the first window loads normally pretty straightforward (the first window consist of multiple buttons that leads to different windows). When I click on any button I get this massive error :

now the last line leads me to this piece of code :
@FXML
public void openInf() throws IOException, ClassNotFoundException {
s = "Informatique";
Stage stg = (Stage) anchorPaneFront.getScene().getWindow();
stg.close();
stg.setResizable(true);
Parent root = FXMLLoader.load(getClass().getResource("inf.fxml"));
Scene scene = new Scene(root);
stg.setScene(scene);
stg.show();
}
What I understand so far is that it can't locate inf.fxml, so I tried to replace it with the full path of the FXML file but the same error occurs, can someone help me understand what is happening and how can I solve it?
