xamarin iphone app crashes on end user's devices - iphone

I completed the development of application and pushed to appstore. I don't know the solution and even don't know why app crashes on end user's devices.
I am able to get the crash logs and here is the logs. Please help me to resolve this unknown crash.

iOS Crash in CLSTerminateHandler()

I'm getting this crash from many devices using my app. I can't see where is the error since Xcode doesn't select any line in the code and the backtrace of the log is quite confusing for me.
The Xcode Organizer selects the error on CLSTerminateHandler(), but can see where in my project.
Here's the crash log:

Crash KVO_IS_RETAINING_ALL_OBSERVERS_OF_THIS_OBJECT_IF_IT_CRASHES_AN_OBSERVER_WAS_OVERRELEASED_OR_SMASHED

I'm seeing crashes in my crash log, but I have yet to experience a crash directly. I've searched everything and tried everything but I'm stuck.
Any ideas on why I'm getting these in my crash logs?

Unable to understand Apple Crash Log with -[UIApplication _cachedSystemAnimationFenceCreatingIfNecessary:]

I'm unable to understand this crash log from Apple. I have been a few times rejected because of this. They are complaining it's occurred on ipad running latest software 10.3.1. When we double check with on ipad simulator, it's running without crashes.

The log clearly shows the problem happens on a background thread. You need to perform UI actions on the main queue. Use DispatchQueue.main.async to dismiss the view controller.

It is particularly crashing "Thread 5 Webthread" Sometimes Thread 8
Any feedback is appreciated :)
I figured out the problem, #Jake Lin's suggestion was right it was the link. I was trying to connect to twitter and I was using the URL: http://mobile.twitter.com/account and I tried changing it to: https://mobile.twitter.com/account where I added the "s" in the http. Very strange problem but that seemed to fix it.
