hello everyone i have made a pyqt5 script and its working very well no i have added the splash screen for my project and the error i am having is that the whole app crashes and doesn't execute except the splash screen. class parameter

class Ui_LOGINpAGE(QObject):
    def __init__(self):
        super(Ui_LOGINpAGE, self).__init__()

    def setupUi(self, LOGINpAGE):
        LOGINpAGE.setObjectName("LOGINpAGE")
'''''''''''''''''
'''''''''''''
''''''''

codes which i am using are for splash screen

if __name__ == "__main__":
    import sys, time

    app = QApplication(sys.argv)

    # Create and display the splash screen
    splash_pix = QPixmap('img/logo.png')

    splash = QSplashScreen(splash_pix, Qt.WindowStaysOnTopHint)
    splash.setWindowFlags(Qt.WindowStaysOnTopHint | Qt.FramelessWindowHint)
    splash.setEnabled(False)
    # splash = QSplashScreen(splash_pix)
    # adding progress bar
    progressBar = QProgressBar(splash)
    progressBar.setMaximum(10)
    progressBar.setGeometry(0, splash_pix.height() - 50, splash_pix.width(), 20)

    # splash.setMask(splash_pix.mask())

    splash.show()
    splash.showMessage("<h1><font color='green'>Welcome BeeMan!</font></h1>", Qt.AlignTop | Qt.AlignCenter, Qt.black)

    for i in range(1, 11):
        progressBar.setValue(i)
        t = time.time()
        while time.time() < t + 0.1:
            app.processEvents()

    # Simulate something that takes time
    time.sleep(5)

    import sys

    app = QtWidgets.QApplication(sys.argv)
    LOGINpAGE = QtWidgets.QMainWindow()
    ui = Ui_LOGINpAGE()
    ui.setupUi(LOGINpAGE)
    print(Ui_LOGINpAGE.__dict__)

    splash.finish(LOGINpAGE.show())
    sys.exit(app.exec_())
