Markdown.ToHtml throws a NullReferenceException when converting the markdown file from the attached archive. You can run the following code to reproduce it (the path variable should contain the path to the extracted file):

var text = File.ReadAllText(path);
var pipeline = new MarkdownPipelineBuilder().UseAdvancedExtensions().Build();
Markdown.ToHtml(text, pipeline);
