Windows phone 8.1 application crashing just after opening share ui

I have 2 pages in my windows 8.1 application. Both of them have a share button. On the first page which is my home page the share button works as it is suppossed to, i.e. open share ui (shown below).

But on my other page (which is has a webview for showing some modified web content) as soon as the share ui opens the app crashes (sometimes before opening). I am not getting any exceptions or errors during execution of program.

When I deploy the app to my phone using Visual Studio it does not crash, but on running the app afterwards (without visual studio) it starts crashing.

This shows how I open share UI (Find Full Code for the page here)

try
{
   Windows.ApplicationModel.DataTransfer.DataTransferManager.ShowShareUI();
}
catch(Exception ex)
{
   //Code to handle exception
}

This is some part of the output when compiling (find full output here)

There is probably a problem with suspending (it's not called when you are debugging).

The best would be if you have tried to debug your suspending events - to do it use Lifecycle events tab in VS (like in the picture in this answer.

The problem may be also that you have passed some parameters when navigating to page that are not serializable. In this case, when the app is being suspended, the SuspensionManager may throw exception.
