Question

我正在使用PyQt构建应用程序GUI，并且有一个功能需要在后台运行，因此我正在使用QThread（请参见下面的代码）。我收到“进程结束，退出代码为-1073740791（0xC0000409）”

该问题如何解决？谢谢

import time

from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QVBoxLayout
from PyQt5.QtCore import pyqtSignal, QThread
import sys

class MyApp(QWidget):
    def __init__(self):
        super(QWidget, self).__init__()
        btn = QPushButton('Run')
        layout = QVBoxLayout()
        layout.addWidget(btn)
        btn.clicked.connect(self.my_function)
        self.setLayout(layout)

    def my_function(self):
        my_task = Task()
        my_task.done_signal.connect(self.done)
        my_task.start()

    def done(self):
        print('done')


class Task(QThread):
    done_signal = pyqtSignal()

    def run(self):
        # Do some work here
        time.sleep(3)
        self.done_signal.emit()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    w = MyApp()
    w.show()
    sys.exit(app.exec_())

带有QThread的GUI因-1073740791（0xC0000409）而崩溃
