python - PyQt5 event filter occassionally not gaining focus when window is deactivated

Question

I want to create a customizedwindow such that whenever window is deactivated. The window becomes the 'active' window and regains the focus to the window

Below code is sort of working but randomly stops making the window 'active' after several window deactivates, when this happens the app just blinks on the bottom of the toolbar or is just highlighted.

(Btw im using windows 7 if it matters)

from PyQt5.QtWidgets import QMainWindow, QApplication
from PyQt5 import QtCore
import sys

class myWindow(QMainWindow):
    def __init__(self, parent=None):
        super(myWindow, self).__init__(parent)
        self.installEventFilter(self)
        self.counter = 0

    def eventFilter(self, obj, event):
        if event.type() == QtCore.QEvent.WindowDeactivate:
            self.counter += 1
            print(self.counter)
            
            self.raise_()
            self.activateWindow()
            return False
        return False


if __name__ == '__main__':
    app = QApplication(sys.argv)
    win = myWindow()
    win.show()
    sys.exit(app.exec())
