I cannot convert a file to ocr with itextocr

Question

I’m trying to create a program that applies ocr to a non-ocr pdf, using the library Itextocr in the .Net.

It turns out I’m having the following error:

I’m venturing into C#, but the code is as follows::

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Windows.Forms;
using System.IO;

//ItextOCR

using iText.Kernel.Pdf;
using iText.Pdfocr;
using iText.Pdfocr.Tesseract4;

namespace PDFParser
{
    public partial class ConvertePesquisavel : UserControl
    {
        private static readonly Tesseract4OcrEngineProperties tesseract4OcrEngineProperties = new Tesseract4OcrEngineProperties();
        public static string PATH_ROOT = System.Environment.CurrentDirectory;
        private static string TESS_DATA_FOLDER = PATH_ROOT + @"\TESSDATA";
        private string OUTPUT_PDF;

        private static IList<FileInfo> LIST_IMAGES_OCR = new List<FileInfo>();       
               

        private void btnOcrSelecionarArquivo_Click(object sender, EventArgs e)
        {
            ocrFileDialog.Filter = "Arquivo jpg | *.jpg";

            if (ocrFileDialog.ShowDialog() != DialogResult.Cancel)
            {
                lblOcrArquivoSelecionado.Text = "Documento selecionado: \n" + ocrFileDialog.FileName;
                this.btnConverterOcr.BackColor = Color.Green;
                
            }
        }

        void OcrConvert()
        {
            var tesseractReader = new Tesseract4LibOcrEngine(tesseract4OcrEngineProperties);

            tesseract4OcrEngineProperties.SetPathToTessData(new FileInfo(TESS_DATA_FOLDER));
            var properties = new OcrPdfCreatorProperties();
            properties.SetPdfLang("por");

            var ocrPdfCreator = new OcrPdfCreator(tesseractReader);

            OUTPUT_PDF = ocrFileDialog.FileName + "ocr.pdf";


            LIST_IMAGES_OCR.Add(new FileInfo(ocrFileDialog.FileName));

            Console.WriteLine(LIST_IMAGES_OCR[0]);

            using (var writer = new PdfWriter(OUTPUT_PDF))
            {                
                ocrPdfCreator.CreatePdf(LIST_IMAGES_OCR, writer).Close();
            }
        }

private void btnConverterOcr_Click(object sender, EventArgs e)
        {
            OcrConvert();
        }
    }

The program appears when the function Ocrconvert is called.

Any help is welcome!
