How to fix the error " Window was already created"?

I successfully implemented and receive the push notifications, but when I tap on the notification message my app started crash getting blank page and at the mean time, I can see the exception,

**System.InvalidOperationException:** 'Window was already created'

Here, i have added the call trace,
