Xamarin.iOS app crashes on startup with iPhone5 when downloaded from app store. DYLD, Library not loaded error.-+

I am working on a Xamarin application. The app works fine when deployed Ad-Hoc on my iPhone5. The App works fine on iPad and iPhone6 both in Ad-Hoc and App Store versions. However, I get an instant crash when I try to start the App Store/TestFlight version on my iPhone 5.
Here is the crash log :

Here is my build config:
I build for ARMv7 + ARM64, with my configuration set to AppStore
I've looked around but most solutions to problems of this nature seem to deal with Swift or XCode and not Xamarin/Visual Studio.
I have tried this solution : https://www.gitmemory.com/issue/xamarin/XamarinComponents/597/520597929 with no success.
I am a beginner when it comes to Xamarin and deploying apps.
Edit:
So it turns out the Frameworks in my .ipa have a info.plist files with a UIRequiredDeviceCapabilities key with the value arm64 which makes Apple's thinning process remove armv7 versions of these frameworks. I have no clue why this key appears in those frameworks however.
Affected frameworks :
MaterialComponents.framework
MDFInternationalization.framework
MDFTextAccessibility.framework
MotionAnimator.framework
MotionInterchange.framework
MotionTransitioning.framework
Unaffected frameworks :
libSkiaSharp.framework

* Bugcheck Analysis *

*******************************************************************************
KERNEL_MODE_EXCEPTION_NOT_HANDLED_M (1000008e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
Arguments:
Arg1: 80000004, The exception code that was not handled
Arg2: ffdff2a5, The address that the exception occurred at
Arg3: a9c34d48, Trap Frame

The service name can be different: av.exe, scvhost.ext,..
I know that is due to the a driver does not process STATUS_SINGLE_STEP exception.
Is any idea how to find wrong driver? There is no stack and module name in the dump...
I tried to run the Mirosoft Driver Verifier with standart flags and all drivers without Microsoft drivers, dump listing is above.

Issue #1: Failed to avformat_open_input 'logo.png'
You are experiencing two separate issues. The message Failed to avformat_open_input 'logo.png' probably indicates that ffmpeg can't find logo.png (or perhaps can't decode it properly). Either provide an absolute path to the file or place it in the same directory (or "folder" I believe is the Windows vernacular) as your ffmpeg binary. If the file is in the correct location then run ffmpeg -i logo.png to see if ffmpeg can even decode it.
Issue #2: No such filter: 'movie'
The second message No such filter: 'movie' indicates that the ffmpeg used in this command is too old and either supports no filters or is simply too old for movie. Binaries from arrozcru.org are outdated. The Zeranoe FFmpeg Builds are kept up to date and are configured sanely. You should go ahead and get a more recent binary while your at it. Revision 36635 is already at least 3696 revisions old. Then take a look at FFmpeg: The ultimate Video and Audio Manipulation Tool for a good overview on usage.
Adding watermark
Anyway, you don't need the movie source filter to add a watermark. See the example in How to add transparent watermark in center of a video with ffmpeg?

Faced the same issue
(Error initializing filter 'movie' with args '/mnt/sdcard/MyApp/frame.png').
Using static ffmpeg library in my android app. On samsung galaxy s3 it works fine, but on the lenovo and htc 2.3.6 i had same error in ffmpeg - he coudln't find my watermark. Fixed this error by moving waterkmark in the same folder as ffmpeg (executable). So now i using next path in movie filter "...movie=frame.png..." instead of "...movie=/mnt/sdcard/MyApp/frame.png". Still don't know is it a bug or i'm just doing something wrong.

Better MonoTouch crashes with TestFlight

We've hooked up TestFlight and the TestFlight SDK with MonoTouch and so far it's working great.
One thing we've noticed is that the crash reports are more geared towards Obj-C apps.
They look like this after you upload a zipped dSYM file:
0 OurApp 0x007a7116 testflight_backtrace + 170
1 OurApp0x007a7c3c TFSignalHandler + 208
2 libsystem_c.dylib 0x34f68538 _sigtramp + 48

17 OurApp 0x0026955b System_Linq_Enumerable_ToList_TSource_System_Collections_Generic_IEnumerable_1_TSource (System.Core.dll.6.s:1917)
So you can tell the general C# function where the crash occurred. (Note: this crash was a bug in MonoTouch 5.0.1 where Linq generics were messed up, seems to be fixed in 5.0.2)
It would be nice to get the full C# stack trace in here, any thoughts on how to do that? I could hook into AppDomain.UnhandledException and put a try-catch around my static void Main method, but wondered if there is a way to report the stack trace out to TestFlight.

I'm not familiar with MonoTouch, but what about using the Remote Logging features of the TestFlight SDK?
