.NET 9 - Fails to recognise .ppt file

In a .NET application, attempting to convert the attached Powerpoint fails with the following conversion code.

ppt file.zip (284.5 KB)

using var converter = new Converter(() => ms);
var convertOptions = new PdfConvertOptions();

converter.Convert(convertOptions, (Action<ConvertedContext>)(context =>
{
    context.ConvertedStream.CopyTo(fs);
}));

It fails with the following error message

Conversion from () to pdf (PDF) is not supported.

I can get around this by getting some default load options using this code. However it was my understanding I could convert without these?

LoadOptions GetLoadOptions(LoadContext context)
{
    var possibleConversions = Converter.GetPossibleConversions(Path.GetExtension(fileToConvert.FileName));
    var loadOptions = possibleConversions.LoadOptions;
    return loadOptions;
}
