Has anyone started getting a problem after upgrading from 4.10.0 ?

I receive "The type initializer for 'Examine.ExamineManager' threw an exception" on code that worked on 4.10.0,

se below, i extraced the value out to a variable for debugging purposes (x), the error occurs when converting node to Media.

@{

    var imageSlides = umbraco.uQuery.GetNode(-1).GetDescendantNodesByType("SlideShowImage").ToList();

    foreach (var doc in imageSlides )
   {
var x = doc.GetProperty("slideImage").Value;
        var m = new umbraco.MacroEngines.DynamicNode(int.Parse(x));

        @:<img src="@m.NiceUrl?width=942&height=350&scale=both" data-thumb="@m.NiceUrl" alt="@doc.GetProperty("imageTitle").Value" title="@doc.GetProperty("imageText").Value"/>

    }
