Не работает код pyqt5 как надо

Question

Здравствyйте, у меня есть код. В котором я хочу сделать функцию. При нажатии кнопки open1 добавляется в gridlayout виджет и фон заблюривается. Так же и со второй кнопкой, токо открывается уже другой виджет. Я хочу сделать так, что при нажатии open1 открывался виджет, в котором я смогу нажать ESC и он закроется и блур пропадет. Так же и со вторым окном. Но почему-то у меня в коде блур пропадает но виджет из gridlayout не закрывается. Как это можно исправить?
