I have strange crashes on devices in my Xamarin App. It happens at any time of app, without any connection to particular actions inside the app. What can I do to find a reason for that crash?
The crash log was caught through HockeyApp.

The debugg information is not clear for the reason the application fail only in release mode.

Fortunately the problem is Entitlement.plist, for some reason when use SecureStorage from Xamarin.Essentials, the application crash in release Testflight on shop, so I remove SecureStorage and problem solved.
Thanks all for all the answers.
I have a WatchOS Application on TestFlight that is crashing on startup on Apple Watch Series 3 devices (32-bit). It works flawlessly on Simulators (Xcode 11.7) and Apple Watch Series 4.
I am using Alamofire 5.2.2 with Swift Package Manager. Latest Xcode (version 11.7). The device is Apple Watch Series 3 devices (32-bit) running latest final watchOS (version 6.2.8). Can you help me or give some direction on what is happening here?
I am calling a REST service that returns a JSON error file (response) and HTTP status code 401 (Unauthorized) if no gateway access token is given.
As I said this works in simulator and Apple Watch Series 4 device. I suspect of Bitcode, as in the past versions I had an iOS companion app and disabled bitcode generation, but now we only have the watch app and I cannot disable Bitcode generation.
The crash is somewhat like this:

This is a known issue
https://github.com/Alamofire/Alamofire/issues/3295
Beyond Apple releasing a fix for their bug -- the work arounds include:
Setting Dead Code stripping to No in the Watch Extension Target.
A different version of Alamofire.
Moving AF from SPM to CocoaPods.
Our Xamarin Forms app is crashing intermittently on one of our iOS test devices, and I'm having a very hard time finding anything useful in the crash report.
All of the tutorials and examples I have found seem to reference line numbers and methods/properties from the application itself but all I am seeing here are mono library calls.
I'm also unable to reproduce the issue locally. Can anyone offer any guidance, or suggest a good resource I could use to determine what this crash report is actually reporting:

What I can see, is that something is going wrong when you try to run some code on the ui thread. The following line tells me this UIKit_UIKitSynchronizationContext__Postc__AnonStorey0__m__0 (UIKitSynchronizationContext.cs:24).
It's very hard to tell exactly what the problem is or in which file the problem is. Maybe implement insights are another crash logger. So you get more info about the crash.
I am using HockeyApp for crash reporting and getting the following crash. I am unable to reproduce the crash. Can this be due to animating the scroll in the UICollectionView?

I got a crash log from an app that is already in App Store. The weird part of the crash log is that a class method appears twice in the backtrace of the crashed thread, as if the class method recursively called itself. I said weird because that class method is quite simple and it doesn't make a recursive call inside method body. Here is the part from the crash log:

Does any one have a reasoning why +[PHAPIRequest expectedSignatureValueForResponse:nonce:secret:] appears twice in the backtrace or may be knows the reason of the crash? Appreciate your help!
