Infinite loop problem on laravel livewire

I'm trying to create a nested tree category system in laravel livewire. Im using kalnoy/laravel-nestedset library. My livewire component codes:

app/Livewire/CategoryTree.php:

namespace App\Livewire;

use Livewire\Component;
use App\Models\Category;

class CategoryTree extends Component
{
    public $categories;
    public $newCategoryName = '';
    public $parentId = null;

    protected $listeners = ['updateOrder' => 'updateOrder'];

    public function mount()
    {
        $this->categories = Category::get()->toTree();
    }

    public function render()
    {
        return view('livewire.category-tree', ['categories' => $this->categories]);
    }

    public function addCategory()
    {
        $this->validate([
            'newCategoryName' => 'required|string|max:255',
        ]);

        $parent = Category::find($this->parentId);
        $category = new Category(['name' => $this->newCategoryName]);

        if ($parent) {
            $parent->appendNode($category);
        } else {
            Category::create(['name' => $this->newCategoryName]);
        }

        $this->resetForm();
        $this->mount();  // Kategorileri yeniden yükle
    }

    public function deleteCategory($id)
    {
        $category = Category::findOrFail($id);
        $category->delete();
        $this->mount();  // Kategorileri yeniden yükle
    }

    public function updateOrder($order)
    {
        $this->saveOrder($order);
        $this->categories = Category::get()->toTree();
    }

    private function saveOrder($order, $parentId = null)
    {
        foreach ($order as $index => $item) {
            $category = Category::find($item['id']);
            $category->parent_id = $parentId;
            $category->save();

            if (isset($item['children'])) {
                $this->saveOrder($item['children'], $item['id']);
            }
        }

        Category::fixTree();  // lft, rgt, depth değerlerini otomatik olarak düzeltir
    }

    private function resetForm()
    {
        $this->newCategoryName = '';
        $this->parentId = null;
    }
}

app/Model/Category.php:

namespace App\Models;
use Kalnoy\Nestedset\NodeTrait;

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

class Category extends Model
{
    use NodeTrait;

    protected $fillable = ['name', 'parent_id'];
}

this line cause the problem: $this->categories = Category::get()->toTree(); when i use the toTree() function, laravel gives this error: the error is Xdebug has detected a possible infinite loop, and aborted your script with a stack depth of '512' frames

if i use toFlatTree() function, script runs without error and i can see Categories.

i have to list categories in tree format. how can i fix this problem?
