New Post: Magick.NET-7.0.0.0009-Q16-x64-net40-client Freezing System

This could easily be something I'm doing, I have the identical below, just for .NET 3.5, and this one is built against .NET 4.5 - so when I run the code below, I completely freeze my system. It's so bad, all I can do is turn the computer off and back on. Event Viewer isn't capturing anything and there are some partial files left behind, but no other error message I can see. Any help would appreciated.

                using (MagickImage image = new MagickImage(sourceName.Value.ToString()))

                    image.Write(string.Concat(targetName.Value.ToString(), ".", fileType.Value.ToString()));
                }

                var returnCollection = new SimpleExpressionValueCollection
                {
                    {"returnValue", new Value("Success: EP called")}
                };

                return new Value(returnCollection);
            }
            catch (Exception ex)
            {
                executionState.Trace("SVGtoPNG: Error - " + ex.StackTrace + ", " + ex.Message);
                Trace.WriteLine("SVGtoPNG: Error - " + ex.StackTrace + ", " + ex.Message);

                var errorCollection = new SimpleExpressionValueCollection
                {
                    {"Description", new Value("Error: " + ex.Message)}
                };

                return new Value(errorCollection);
            }

            //throw new NotImplementedException();
        }
    }
}
