PyQT5 Python 3.12 gif overlay

Question

There are problems using the QTimer function. In the class initialization after the timer ran, the window is hidden successfuly, but if I try to call it inside the show_window function, the window is not hidden.

import sys
import keyboard
from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5.QtCore import Qt, QTimer
from PyQt5.QtGui import QMovie, QCursor
from PyQt5.Qt import QLabel, QSize

 
class Example(QWidget):
    def __init__(self):
        super().__init__()
        cursor_pos = QCursor().pos()
        screen_number = QApplication.desktop().screenNumber(cursor_pos)
        screen_rect = QApplication.desktop().availableGeometry(screen_number)
        w_width = screen_rect.width()
        w_height = screen_rect.height()
        print(w_width, w_height)

        keyboard.on_press(self.show_window)
        self.timer = QTimer(self)
        self.timer.timeout.connect(self.hide)
        self.timer.start(5000)

        self.setWindowTitle('Gif_overlay')
        self.setGeometry(screen_rect.right() - w_height//4, screen_rect.bottom() - w_height//4,
                         w_height//4, w_height//4)
        self.setAttribute(Qt.WA_TranslucentBackground, True)
        # self.setWindowFlags(Qt.FramelessWindowHint)
        self.setWindowFlag(Qt.WindowStaysOnTopHint)

        self.label = QLabel(self)
        movie = QMovie("1.gif")
        gif_size = (w_height//4, w_height//4)
        movie.setScaledSize(QSize(*gif_size))
        self.label.resize(*gif_size)
        self.label.setMovie(movie)
        self.label.move(0, 0)
        movie.start()

    def show_window(self, key):
        if not (self.isVisible()):
            self.show()
            self.timer.start(5000)
        else:
            self.timer.setInterval(5000) 


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

I use python 3.12, the library version below
