Adding this “–module-path “C:\Program Files\Java\javafx-sdk-21.0.3\lib” --add-modules javafx.controls,javafx.fxml” to VM options and deleting “module-info” file options fix my problem. But can any1 explain to me the problem I’m facing

@Migel077 this is likely due to the need to update the predefined definitions in the list of packages in M2.1.

I believe I’ve already tackled this on master.
