Android: iText PdfReader throws IOException not found as file or resource

I have a problem using iText. when I create a PdfReader always the same problem: IOException, not fount as file or resource.

  String ficherosAuxiliaresDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/FG/FicherosInternos/Auxiliares/";

            String src = ficherosAuxiliaresDir + "descuentosform.pdf";
            String dest = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/FG/FicherosInternos/Descuentos/" + clienteSeleccionado.getIdCliente() + "-Hoja de descuentos-ForestalGarden.pdf";

            //Fuente
            String fuente = ficherosAuxiliaresDir + "robotomonoregular.ttf";

            myFilePdf = new File(dest);

            PdfDocument pdfDoc = new PdfDocument(new PdfReader(src), new PdfWriter(dest));

however if I try:

File f = new File(src);
boolean b = f.exists();

Here b = TRUE, so file is there, app can access to it....... where is the problem? In fact on my previous code PdfWriter(dest) works fine.

Here the stack trace:

java.io.IOException: /storage/emulated/0/Download/FG/FicherosInternos/Auxiliares/descuentosform.pdf not found as file or resource.

SOLVED

It was a problem of permission. I modified to SDK 31 so I had to ask for a full access permission, this is the reason it works before (SDK26) and fail now. So just added:

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
                if (Environment.isExternalStorageManager()) {
                    //todo when permission is granted
                } else {
                    //request for the permission
                    Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION);
                    Uri uri = Uri.fromParts("package", getPackageName(), null);
                    intent.setData(uri);
                    startActivity(intent);
                }
            }

And it works great. I just post the solution just in case someone have the same problem.
