Python 使用 QPainter.drawLine() 时 PySide6 应用程序崩溃

在Windows 10，python3.10上，当调用QPainter.DrawLine()时，PySide6(或PyQt6)QApplication崩溃.

终端只显示:

进程已完成，退出代码为-1073741819(0xC0000005)

请查看下面的代码:

import sys
from PySide6.QtCore import QPoint, Qt
from PySide6.QtGui import QColor, QPainter, QPen, QPixmap
from PySide6.QtWidgets import QApplication, QLabel, QMainWindow


# from PyQt6.QtCore import QPoint, Qt
# from PyQt6.QtGui import QColor, QPainter, QPen, QPixmap
# from PyQt6.QtWidgets import QApplication, QLabel, QMainWindow

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.label = QLabel()
        canvas = QPixmap(400, 300)
        canvas.fill(Qt.GlobalColor.white)

        self.label.setPixmap(canvas)
        self.setCentralWidget(self.label)
        self.draw_something()

    def draw_something(self):
        painter = QPainter(self.label.pixmap())
        painter.drawLine(10, 10, 300, 200)  # >=========== Crash Here
        painter.end()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    app.exec()
