Xamarin.iOS - Error processing Custom Renderer method

Question

I've been trying to get a build archived for IOS by using Visual studio and the "Pair to mac" functionality.
However, when I try and do a release build, I get this error:

Error processing the method 'System.Void ProjectName.iOS.Renderers.IOSWebViewRenderer::.ctor()' in the assembly 'TextFlowMobile.iOS.exe': Object reference not set to an instance of an object TextFlowMobile.iOS

My code for this renderer, that is for WKWebView is as follows:

`[assembly: ExportRenderer(typeof(WebView), typeof(IOSWebViewRenderer))]  
namespace TextFlowMobile.iOS.Renderers  
{  
    public class IOSWebViewRenderer : WkWebViewRenderer  
    {  
        public override WKNavigation LoadHtmlString(NSString htmlString, NSUrl baseUrl)  
        {  
            try  
            {  
                if(htmlString != null && baseUrl != null)  
                {  
                    // Add additional HTML to ensure fonts scale correctly and don't appear extremely small and almost unreadable  
                    var iOSHtmlWithScaling = htmlString.ToString().Insert(0, "<meta name='viewport' content='width=device-width,initial-scale=1,maximum-scale=1' />");  
                    return base.LoadHtmlString((NSString)iOSHtmlWithScaling, baseUrl);  
                }  
                else  
                {  
                    return base.LoadHtmlString(htmlString, baseUrl);  
                }  
            }  
            catch (Exception)  
            {  
                //System.Diagnostics.Debug.WriteLine(ex);  
                return base.LoadHtmlString(htmlString, baseUrl);  
            }  
        }  
    }  
}`  

As you can see, I don't override the constructor at all. I really don't see why this happens, especially since it builds (and deploys on a simulator on the connected mac) perfectly fine for debug.

My current config is Release | iPhone | ProjectName.iOS | Remote Device

I really appreciate any help!

This error occurred because I had an Obfuscator running on the release version of the code. When I tried to archive this, I imagine it couldn't properly compile this renderer because it was obfuscated.
