Ниже приведен мой xml-файл. В предварительном просмотре есть две ошибки 'failed для загрузки AppCompat ActionBar с неизвестной ошибкой' & 'не удалось создать более одного класса'. Как я могу запустить приложение.Но приложение аварийно завершает работу и в Logcat не отображаются ошибки.

Это мой предварительный снимок экрана
