other it's ok, when I test branch pyqt5. it's error when I test branch Pyside6

Maybe it's caused by the Python version, my 3.8.16 and 3.11.0 python won't have this problem.

安装3.8.16好了

@dwincxy 把 qfluentwidgets/components/dialog_box/dialog.py 的 Ui_MessageBox 的类定义为 class Ui_MessageBox 而非 QObject 的子类，可以解决此问题吗

@zhiyiYo 不好意思，忘记回复了，后面我装环境直接用python官方源就好了，很多问题都是用了镜像源的原因，后面Pyqt5 和 Pyside6版本我试了都可以了
