JSON Parsing - deadlock/stuck on parsing Json to HTML

Comienza en el método Parse mostrado en el issue y reproduce el bloqueo con la cadena JSON proporcionada, HtmlFormatter y el lenguaje json de ColorCode.Languages.FindById. Sigue la expresión regular compilada del lenguaje a través de regexMatch.NextMatch() y verifica que el análisis se complete sin quedarse bloqueado y que siga produciendo la salida HTML esperada.

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
