Integrating IronPdf crashes unity

Question

I worked with itextpdf which worked well with unity, but i had to switch to IronPdf as i needed to work with arabic, which was a problem because it needed an itextpdf add-on that wasn't free.

Anyway IronPdf seemed to work well when i tried it on a console app, but unity freezes as soon as i call the function that has the code.

 using System;
 using System.Collections;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using System.Threading.Tasks;
 using System.IO;
 using UnityEngine;
 using UnityEngine.UI;
 using TMPro;
 using IronPdf;
 
 public class ConvertPDF : MonoBehaviour
 {
     public TextMeshProUGUI txt;
     
 
     public void Nothing()
     {
         Debug.Log("Nothing");
     }
     
     public void Html2PDF()
     {
         Debug.Break();
         string msg = "";
         try
         {
             
             IronPdf.HtmlToPdf Renderer = new IronPdf.HtmlToPdf();
             IronPdf.PdfDocument PDF = Renderer.RenderHTMLFileAsPdf("input.html");
             string OutputPath = "output.pdf";
             PDF.SaveAs(OutputPath);
             msg = "Generated to " + OutputPath;
         }
         catch (Exception e)
         {
             msg = e.Message;
         }
         txt.text = msg;
         Debug.Log(msg);
     }
 }

I call this function when a button is pressed and unity crashes even though i added the dll of the library to unity the same way i did with itextpdf.

Edit:
I got in touch with the IronPDF developers, here is the answer:

"Currently Unity 3D isn't supported by IronPDF but it is something we plan on releasing for out next update."

I have got the same problem. Editor/Application freezes, in the logfile it says:

I made a simple testapplication with WPF and there runs IronPDF like a charm.
