Image cannot be loaded. Available decoders

Question

Trying to load a image with ImageSharp, I get this: Image cannot be loaded. Available decoders:

• BMP : BmpDecoder
• GIF : GifDecoder
• PBM : PbmDecoder
• JPEG : JpegDecoder
• PNG : PngDecoder
• TGA : TgaDecoder
• Webp : WebpDecoder
• TIFF : TiffDecoder

I try to load in 2 ways. The first is with this method, this received a byte array from other method where I load with a File System.

private byte[] FileToSizedImageSource1(String file, int width, int height)
    {
        byte[] data = File.ReadAllBytes(file);
        return this.FileToSizedImageSource2(data, width, height);
    }

private byte[] FileToSizedImageSource2(byte[] data, int x, int y)
    {
        byte[] result = null;
        using (MemoryStream memoryStream = new MemoryStream(data))
        {
            memoryStream.Seek(0, SeekOrigin.Begin);
            memoryStream.Position = 0;
            var raw = Image.Load(memoryStream);
            var clone = raw.Clone(context => context
                        .Resize(new ResizeOptions
                        {
                            Mode = ResizeMode.Max,
                            Size = new Size(x, y)
                        }));
            using (MemoryStream ms = new MemoryStream())
            {
                ms.Position = 0;
                clone.Save(ms, new PngEncoder { CompressionLevel = PngCompressionLevel.DefaultCompression });
                byte[] img_buffer = ms.ToArray();
                result = Compress(img_buffer);
            }
        }
        return result;
    }

And the other way is loading with the own ImageSharp

private byte[] FileToSizedImageSource2(string path, int x, int y)
    {
        byte[] result = null;
        using (var raw = Image.Load(path))
        {
            var clone = raw.Clone(context => context
                        .Resize(new ResizeOptions
                        {
                            Mode = ResizeMode.Max,
                            Size = new Size(x, y)
                        }));
            using (MemoryStream ms = new MemoryStream())
            {
                ms.Position = 0;
                clone.Save(ms, new PngEncoder { CompressionLevel = PngCompressionLevel.DefaultCompression });
                byte[] img_buffer = ms.ToArray();
                result = Compress(img_buffer);
            }
        }
        return result;
    }
