Hello friends I'm still stuck with this, someone can help me out ... This is my error:

These are my models and my htmlCs

//kyo es el nombre de mi vista, este es el controller
        //GET: Home/kyo
        [Authorize]
        public ActionResult Kyo( )
        {
            
              return View();
        }

With this I am calling the models I want my data from

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using PCotiza_compras.Models;


namespace PCotiza_compras.Models
{
    public class ReqCatDep
    {
        public List<PCotiza_compras.Models.Departments> Dep { get; set; }
        public List<PCotiza_compras.Models.Categories> Cat { get; set; }
        public List<PCotiza_compras.Models.Requests> Req { get; set; }

    }
}

And this is my view:

@model PCotiza_compras.Models.ReqCatDep

@{
    ViewBag.Title = "Kyo";
}


<div class="panel-group" id="accordion">
  <td>

      @foreach (var item in Model.Cat)
      {
          <tr>
              @item.Name
          </tr>
          <tr>
              @item.Description
          </tr>
      }

     
  </td>

</div>

Thanks to everyone:)

Brother, I see that you have several problems, we are going to solve them:

[Authorize]
public ActionResult Kyo( )
{
    //Aqui te hace falta tu modelo.
    var modelo = llamas a tu base de datos, a la tabla que deseas.
    modelo.cat = lista de elementos
    return View(modelo);
}

Check this code: link has a simple 3 layer project + database. The YouTube video explained in detail how ASPnet MVC works.

You are not passing the model to your eyes, you should do something like this:

    [Authorize]
    public ActionResult Kyo( )
    {
          // Debes crear la logica para llenar el modelo y pasarlo a la vista
          var model = LlenarReqCatDep();


          return View(model);
    }

Obvious that for your code to be of the best quality, you must validate that the data required by the view are in the model.

Happy afternoon as you use razor to do the foreach you can also do an if to verify before crossing if your object is null

@model PCotiza_compras.Models.ReqCatDep

@{
    ViewBag.Title = "Kyo";
}


<div class="panel-group" id="accordion">
  <td>
      @if(Model != null && Model.Cat != null)
      {
        @foreach (var item in Model.Cat)
        {
            <tr>
                @item.Name
            </tr>
            <tr>
                @item.Description
            </tr>
        }
      }     
  </td>

</div>

in this way you will not have that error but you must fill the list in the controller
