Если на скрине плохо видно то вот эта ошибка текстом:
java: cannot access javafx.application.Application
bad class file: /D:/JavaFx 21/javafx-sdk-21.0.4/lib/
javafx.graphics .jar!/javafx/application/Application.class
class file has wrong version 61.0, should be 55.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
