JSON Parsing - deadlock/stuck on parsing Json to HTML

Commencez par la méthode Parse présentée dans l’issue et reproduisez le blocage avec la chaîne JSON fournie, HtmlFormatter et le langage json de ColorCode.Languages.FindById. Suivez l’expression régulière compilée du langage à travers regexMatch.NextMatch() et vérifiez que l’analyse se termine sans rester bloquée tout en produisant toujours la sortie HTML attendue.

Im trying to parse this JSON sipped to my Blazor page. But because of some weird RegEx parsing issue the process get stuck without any Exception. Can somebody tell me where there could be a Problem?
here you can find my test project: ColorCodeTest

This is my Test Code

string _jsonString3 = "{\r\n \"raw_causes\": [\r\n      \"Winterglatter Fahrbahn\",\r\n      \"Nicht angepasste Geschwindigkeit\",\r\n      \"test3\"\r\n    ]\r\n      }";
try
{
    var _formatter = new HtmlFormatter();
    var language = ColorCode.Languages.FindById("json");
    _jsonHtml = _formatter.GetHtmlString(_jsonString3, language);

}
catch (Exception)
{

    throw;
}

It stuck after the array Element \"Winterglatter Fahrbahn\", when it call regexMatch = regexMatch.NextMatch(); and I have no idear why this happends

            if (!regexMatch.Success)
