Unity 5.3beta6 IAP error when running the app

I have implemented Unity IAP in one of my projects for iOS. Tested it on Unity Editor and logs look fine.

When I build it on my phone, after a couple of seconds or so, the app freezes.

Here is the Xcode Log:

After this, nothing shows up and the app remains frozen. Some help sorting this issue would be great :-).

The lockup may not be caused by Unity IAP, the timing of the last logging statement may be coincidental.

Can you pause the application in the xcode debugger and send a screenshot of the stack trace of the main thread?

Thank you for the response. Have attached the screenshot.

This started happening after incorporating Unity IAP. Strangely, there is no crash as such, just that the app freezes.
