'PySide2.QtCore.Qt.WindowType' object cannot be interpreted as an integer

[coder-free]

when I run command python -m AlphaZeroGUI.main. I got this error:

  File "/home/zbf/Desktop/git/github/alphazero-general/AlphaZeroGUI/_gui.py", line 86, in __init__
    self.setWindowFlags(QtCore.Qt.WindowMinimizeButtonHint | QtCore.Qt.WindowCloseButtonHint)
TypeError: 'PySide2.QtCore.Qt.WindowType' object cannot be interpreted as an integer

code is:

class Ui_FormMainMenu(QtWidgets.QMainWindow):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.setWindowFlags(QtCore.Qt.WindowMinimizeButtonHint | QtCore.Qt.WindowCloseButtonHint)
        self.setupUi(self)

    def setupUi(self, FormMainMenu):
        FormMainMenu.setObjectName("FormMainMenu")
        FormMainMenu.resize(876, 647)
        ......

I can't fix this bug. I run it on python 3.11

I change to python 3.8 it worked fine.
