This won't work because base_url() gets initialized if a Controller is loaded. And pre_controller basically means the opposite.

There are two options for you

Option 1

create a PreControllerHook.php in your application/hooks/ directory.

class PreControllerHook extends CI_Controller
{
    public function initialize()
    {
        $controller_name = $this->router->fetch_class();  
        //... and so on
    }
}

Setup your hooks.php config

$hook['pre_controller'] = [
    [
        'class' => 'PreControllerHook',
        'function' => 'initialize',
        'filename' => 'PreControllerHook.php',
        'filepath' => 'hooks'
    [
];

Option 2

create a PostControllerConstructorHook.php in your application/hooks/ directory.

class PostControllerConstructorHook
{
    public function initialize()
    {
        $ci = get_instance();
        $controller_name = $ci->router->fetch_class();  
        //... and so on
    }
}

Setup your hooks.php config

$hook['post_controller_constructor'] = [
    [
        'class' => 'PostControllerConstructorHook',
        'function' => 'initialize',
        'filename' => 'PostControllerConstructorHook.php',
        'filepath' => 'hooks'
    [
];
