App shutting down on dismiss

[Yanis01]

Hello,

I am developing an application on Windows 10. The notification is working well, but whenever I click on the close button, send the notification to the notification center, open it and click on the close button again to totally dismiss the notification from the notification center the application crashes.

I tried to make the notification not appear in the notification center using windows settings, but if I do it this way then the application will crash the first time I close and dismiss the notification.
