    Description

      I have the following minimum test code

      from PySide6.QtCore import *
from PySide6.QtWidgets import *
from PySide6.QtWidgets import *


class Ui_Form(object):
    pass


class Mixin:
    def __init__(self, **kwargs) -> None:
        super().__init__(**kwargs)


class Card(Mixin, QWidget):
    def __init__(self, parent=None) -> None:
        super().__init__(parent=parent)


class Demo(Card, Ui_Form):
    def __init__(self) -> None:
        super().__init__()


app = QApplication([])
d = Demo()

      And this code will get

      TypeError: object._init_() takes exactly one argument (the instance to initialize)

      in PySide6.6.2 but work correctly in PySide6.4.2
