JSON Parsing - deadlock/stuck on parsing Json to HTML

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](https://github.com/JochnGst/ColorCodeTest)

This is my Test Code
```csharp
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
```csharp
private void Parse(string sourceCode,
CompiledLanguage compiledLanguage,
Action> parseHandler)
{
Match regexMatch = compiledLanguage.Regex.Match(sourceCode);

if (!regexMatch.Success)
parseHandler(sourceCode, new List());
else
{
int currentIndex = 0;

try
{
while (regexMatch.Success)
{
string sourceCodeBeforeMatch = sourceCode.Substring(currentIndex, regexMatch.Index - currentIndex);
if (!string.IsNullOrEmpty(sourceCodeBeforeMatch))
parseHandler(sourceCodeBeforeMatch, new List());

string matchedSourceCode = sourceCode.Substring(regexMatch.Index, regexMatch.Length);
if (!string.IsNullOrEmpty(matchedSourceCode))
{
List capturedStylesForMatchedFragment = GetCapturedStyles(regexMatch, regexMatch.Index, compiledLanguage);
List capturedStyleTree = CreateCapturedStyleTree(capturedStylesForMatchedFragment);
parseHandler(matchedSourceCode, capturedStyleTree);
}

currentIndex = regexMatch.Index + regexMatch.Length;
regexMatch = regexMatch.NextMatch();
}
}
catch (Exception ex)
{

throw;
}

string sourceCodeAfterAllMatches = sourceCode.Substring(currentIndex);
if (!string.IsNullOrEmpty(sourceCodeAfterAllMatches))
parseHandler(sourceCodeAfterAllMatches, new List());
}
}

```
