Multiple inheritance with Python class that inherits from QObject results in Seg fault

from PySide6.QtWidgets import QApplication, QWidget
from PySide6.QtCore import QObject

class Test1(QObject):
    pass

# Inheriting directly from QObject will fail with a type error.
class Crashing(Test1, QWidget):
    pass

app = QApplication([])
window = Crashing()
window.show()
app.exec()
