pyqt5 拖拽页面崩溃Process finished with exit code -1073740940 (0xC0000374)

先说一下环境 win10 python3.7.7 PyQt5 5.14.2
用QtDesigner做了个页面

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.verticalLayout = QtWidgets.QVBoxLayout(self.centralwidget)
        self.verticalLayout.setObjectName("verticalLayout")
        self.label = QtWidgets.QLabel(self.centralwidget)
        self.label.setStyleSheet("")
        self.label.setObjectName("label")
        self.verticalLayout.addWidget(self.label)
        MainWindow.setCentralWidget(self.centralwidget)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.label.setText(_translate("MainWindow", "TextLabel"))

然后起线程循环将5张图片写入页面的label中

import time
from threading import Thread
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
import sys
from ui.main_page import Ui_MainWindow


class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super().__init__(parent)
        super().setupUi(self)
        self.label.setScaledContents(True)
        thread = Thread(target=self.background_receiver, args=(self.label,), daemon=True)
        thread.start()

    def background_receiver(self, pic_label):
        files = ("D:\\material\\avatar\\baomao.jpeg",
                 "D:\\material\\avatar\\isu.jpeg",
                 "D:\\material\\avatar\\meng.jpeg",
                 "D:\\material\\avatar\\van.jpeg",
                 "D:\\material\\avatar\\yeah.jpeg",)
        while True:
            for file in files:
                image = QPixmap()
                image.load(file)
                pic_label.setPixmap(image)
                time.sleep(0.25)

app = QApplication(sys.argv)
m = MainWindow()
m.show()
sys.exit(app.exec_())

启动没有问题，但是只要拖拽改变窗口大小，页面就会崩溃
