Ci4 Base controller vs Controller

Your BaseController should be:

PHP Code:

<?php
...

class BaseController extends Controller
{
    ...

    /**
    * An array of helpers to be loaded automatically upon
    * class instantiation. These helpers will be available
    * to all other controllers that extend BaseController.
    *
    * @var array
    */
    protected $helpers = ['form'];

    ....
} 


And your controllers must extend BaseController.
