QCoreApplication in foreground service

[AshkanV]

I created a graphical app using PySide6 and QML and deploys it to Android which works fine, I also created foreground services in python-only code and they also work fine, but when I create a foreground service which uses QCoreApplication for some QtCore stuffs like signal and slot and event-loop management, the moment I create the QCoreApplication, the service crashes with a crash dump in log-cat

Can anyone guide me why this is happening and how can i use the Pyside6 and QCoreApplication inside a foreground service?

Thanks
