Arabic font access violation

I'm trying graphics mill capabilities with google's Noto family of fonts. All the different Unicode fonts like Japanese, Korean..etc works perfectly except Arabic.

I used Noto Kufi Arabic font for this language and when the program hits the MeasureString function, it gives this error:

System.AccessViolationException occurred

HResult=0x80004003

Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Source=<Cannot evaluate the exception source>

StackTrace:

at Aurigma.GraphicsMill.AdvancedDrawing.Text.GetBlackBox()

at Aurigma.GraphicsMill.AdvancedDrawing.Font.MeasureString(String value)

My font creation is like this:

var fontArabic = new CustomFontRegistry(FontRegistry.Installed);
fontArabic.Add(@"C:\Windows\Fonts\NotoKufiArabic-Regular.ttf");
var testfont = fontArabic.CreateFont("Noto Kufi Arabic", "Regular", 24, graphics.DpiX, graphics.DpiX);
var noMeasure = testfont.MeasureString("وضع نقطة في دائرة رقم الخاص بك الرقم بالنظر إلى الإشارة. نقطة واحدة في كل مربع. اتركه فارغاً ل 0");

Am I doing wrong or is there a bug for Arabic? I'm using the latest version.
