Hi,

I already posted the code snippet, but here is a simplified version
including the main function that installs the event filter to the QApplication:
------
import sys
from PyQt5.QtCore import QAbstractNativeEventFilter
from PyQt5.QtWidgets import QApplication

class WinEventFilter(QAbstractNativeEventFilter):
        def nativeEventFilter(self, eventType, message):
            return False, 0

if __name__ == "__main__":
    app = QApplication(sys.argv)
    win_event_filter = WinEventFilter()
    app.installNativeEventFilter(win_event_filter)
    sys.exit(app.exec_()) 
-----

Whoever calls the WinEventFilter.nativeEventFilter, 
from the PyQt framework crashes when the function returns.

BR, Antti

Then I need a simple, complete example that demonstrates the problem.
