App is crashing while trying to launch from the Toast notification

Hi,

Am developing a windows 8.1 app (C#). Here am using TimeTrigger background tasks. Inside that Run method of the background task, am scheduling toast notifications, once in every 2 mins.

Once installed, the app is firing toasts as expected.

Here am facing an issue. If I ignore the first toast, then click on the second toast, the app is crashing. But if I click on the first toast, the app is launching properly without any problem.

I don't understand whats the problem here?

Any help is really appreciable

Thanks

Rajesh
