Getting FFMPEG version error, everytime I press Conversion.start

[lovebif4ever]

Should be some pretty basic code,

var conversion = await FFmpeg.Conversions.FromSnippet.ToWebM(fileToConvert.FullName, outputFileName);

                conversion.OnProgress += async (sender, args) =>
                {
                    //Show all output from FFmpeg to console
                    Debug.WriteLine($"[{args.Duration}/{args.TotalLength}][{args.Percent}%] {fileToConvert.Name}");
                };


                await conversion.Start();

but no matter what I do, I get an exception, when I try to use the Conversion.start method.
