JAR Netbeans не работает / не открывается должным образом

Я сделал игру Hangman с графическим интерфейсом, и я хотел бы построить для нее банку. В Netbeans я перехожу к Run> Clean and Build Project, и, похоже, он просто создает банку. Однако, когда я на самом деле иду, чтобы запустить банку, все, что она делает, открывает крошечное окно в верхнем левом углу экрана, а не графический интерфейс, который я создал. Хотя, когда я запускаю графический интерфейс в Netbeans, он открывается так, как должен. Кроме того, когда я пытаюсь закрыть это окно, которое оно открыло, оно фактически не завершает процесс java - он остается включенным, пока я не закончу его из диспетчера задач. Фотографии и код будут представлены ниже.

Это то, что открывается, когда я запускаю банку - пустой кадр, в котором ничего нет.

Это то, что должно открыться, и это открывается, когда я запускаю проект изнутри Netbeans.

Я попытался запустить его через командную строку, и он работает аналогично без ошибок. Вот мой код:
