lavavel - Undefined Variable $dcategories

I an following an on-line tutorial using Laravel - Livewire. I have spent countless hours in trying to fix an and Undefined variable error. The code and structure is as follows:

Models DirectoryCategory.php

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class DirectoryCategory extends Model
{
    use HasFactory;
}

Livewire Class AdminDashboardDirectoryCategoryComponent.php

<?php

namespace App\Http\Livewire\Admin;

use App\Models\DirectoryCategory;
use Directory;
use Livewire\Component;
use Livewire\WithPagination;

class AdminDashboardDirectoryCategoryComponent extends Component
{
    use WithPagination;
    public function render()
    {
        $dcategories = DirectoryCategory::paginate(10);
        return view('livewire.admin.admin-dashboard-directory-category-component',['dcategories'=>$dcategories])->layout('livewire/admin.admin-dashboard-directory-category-component');
    }
}

view admin-dashboard-directory-category-component.blade.php

<thead>
                                        <tr>
                                            <th>#</th>
                                            <th>Image</th>
                                            <th>Group</th>
                                            <th>Title</th>
                                            <th>Slug</th>
                                            <th>Desc</th>
                                    </thead>
                                    <tbody>
                                        @foreach($dcategories as $dcategory)
