PdfFormatProvider Export - NullReferenceException

[Jonas]

Hello, I'm trying out the DevCraft trial to do conversion from pdf to pdfa, however the .Export method throws a nullreference exception far inside the Telerik-components. Not sure how to proceed, since the error tells me nothing.

I followed the example shown here: https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/howto/comply-with-pdfa-standard

The exception thrown:

The type initializer for 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.ColorSpaces.IccProfileObject' threw an exception.

My code:

public string ConvertToPdfa(string base64)
{
    PdfFormatProvider provider = new PdfFormatProvider();
    var document = provider.Import(Convert.FromBase64String(base64));

    PdfExportSettings settings = new PdfExportSettings();
    settings.ComplianceLevel = PdfComplianceLevel.PdfA2B;
    provider.ExportSettings = settings;

    return Convert.ToBase64String(provider.Export(document));
}

This is a .net5.0 asp.net core application btw.

Hey, 

This is being fixed for the next release, but to work around it I downgraded my assemblies to 118.

Thank you for your reply, that works for me!
