Crash in .net Runtime SDK on iOS device

[CalebPourchot]

I'm getting this crash dump reported from my microsoft App Center logs. My iOS app is built with Xamarin.Forms on .net using the 100.2.1 version of the runtime SDK. I have no repro case for it. It is occurring on iOS 11.3.1. I'm hoping the crash dump will tell you guys something useful. I don't expect an answer. 

Thanks!

Caleb
