Really strange.
First make sure you have correctly copy/pasted your error from your log file or your error screen

Next make sure the file that cannot be loaded is uploaded correctly

This is an example contents of the application/helpers/ directory

So now you’re mixing up problems.
For your upload problems try this version:

github.com

InvoicePlane/InvoicePlane/blob/3bd951de58bee589de93a08dbbcfc16eb4743ccf/application/modules/upload/controllers/Upload.php

<?php

if (! defined('BASEPATH')) {
    exit('No direct script access allowed');
}

 */

#[AllowDynamicProperties]
class Upload extends Admin_Controller
{
    public $targetPath;

or this version:

<?php

if ( ! defined('BASEPATH')) {
    exit('No direct script access allowed');
}

    public $targetPath = UPLOADS_CFILES_FOLDER; // UPLOADS_FOLDER . 'customer_files/';

Finally found what was supposed to be loaded.
It’s this path:

So application/modules/ is missing from your error message which is really strange
