Call to undefined method DateTime :: getTimezone () error laravel Carbon

I am trying to show the date in laravel with a specific format using $casts in my model, but when I show in the view I get an error

Call to undefined method DateTime :: getTimezone ()

and I do not know why this error is due.

Model

class Category extends Model
{
    use  SoftDeletes;

   protected $dates = [ 'created_at','updated_at','deleted_at'];

   protected $casts = [
        'created_at' => 'datetime:d-M-Y H:i:s',
        'updated_at' => 'datetime:d-M-Y H:i:s',
        'deleted_at' => 'datetime:d-M-Y H:i:s'
    ];
