SIGABRT error in Xamarin.Forms app

Question

I have a Xamarin.Forms application that we are ready to deploy to production but I keep getting this SIGABRT error. I've setup a HockeyApp to monitor any crash that may occur. It seems that this error keeps on appearing crash or not. I've included the upper portion of the stack trace that I don't know how to interpret. Can any body help me interpret what this is? Thank you

I've have had the same error before HockeyApp NuGet package or any NuGet package can have the same error I am not sure if it a Linking error, try to turn off the linker ("Don't link") if that does not work try to use a different version of HockeyApp (3.7.1.0) works fine for me.

The problem may persist tho, if you are handling code inside the AppDelegate or the MainActivity check the App lifecycle (OnResume, OnStart, OnSleep and so on).

I can see in the logs: "This app can't run in background" So verify and double check if your code is handling correctly the App Lifecycle and transitions, it may be related to a lot of things (notifications, components, NuGets, Lifecycle, threads, async/await calls)

Hope this helps.
