Project (redacted) and Output.log

I'm regularly getting...

The "LinkAssemblies" task failed unexpectedly.
Mono.Linker.MarkException: Error processing method: 'Android.Views.View Xamarin.Forms.Platform.Android.TextCellRenderer::GetCellCore(Xamarin.Forms.Cell,Android.Views.View,Android.Views.ViewGroup,Android.Content.Context)' in assembly: 'Xamarin.Forms.Platform.Android.dll' ---> System.ArgumentNullException: Value cannot be null.
Parameter name: instruction
   at Mono.Cecil.Cil.InstructionOffset..ctor(Instruction instruction)
   at Mono.Cecil.Cil.CodeReader.ReadScope(ScopeDebugInformation scope)

I'm building ARM & x86 with ProGuard disabled and Linking set to "Sdk Assemblies Only".  Works fine with Linking set to None and I can usually get the project to successfully build and deploy after Clean Solution, but not when rebuilding.  However, I've never been able to successfully Archive because that seems to kick off two builds, and the 2nd one always fails.
