CodeIgniter 4.1.1 PHP7.4.4

Cannot get module views to work:

http://localhost/Airports/moduleTest results in:
viewException:
Invalid file: Bobk\airports\views\moduleTest.php

This is the setup.

I've created my namespace called 'Bobk' in app/Config/Autoload.php

Code:
// app/Config/Autoload.php

public $psr4 = [

 APP_NAMESPACE => APPPATH, // For custom app namespace

 'Config'      => APPPATH . 'Config',

 'Bobk'          => ROOTPATH.'Bobk'

 ];

In folder ROOTPATH/Bobk I have a module folder called 'airports'
airports/controllers/Airports.php
airports/models/Airport_model.php (not used to show problem)
airports/views/moduleTest.php

My airports/controllers/Airports.php file:

Code:
<?php namespace Bobk\Airports\controllers;

use App\Controllers\BaseController;

use Bobk\Airports\models\Airport_Model;

class Airports extends BaseController 

{

.......

    public function moduleTest()

    {

        $data['title']="Module View";

        echo view('Bobk\airports\views\moduleTest', $data);

    }

}

// app\Config\routes.php

Code:
/*

* --------------------------------------------------------------------

* Route Definitions

* --------------------------------------------------------------------

*/

$routes->get('/', 'Home::index');

$routes->get('Airports/moduleTest', '\Bobk\airports\Controllers\Airports::moduleTest');

// ROOTPATH/Bobk/airports/views/moduleTest.php

Code:
<html>

<head>

</head>

<body>

<h2><?= esc($title) ?></h2>

<h3>Hello</h3>

</body>

</html>

THE PROBLEM
// system/View/View.php LINE:195

Code:
if (! is_file($this->renderVars['file']))

{

     $this->renderVars['file'] = $this->loader->locateFile($this->renderVars['view'], 'Views', empty($fileExt) ? 'php' : $fileExt);

This call to locateFile() has the $folder argument set to the literal string 'Views'
This results in the resolved view path being:

ROUTEPATH\Bobk\/Views/airports/views/moduleTest.php"

(I've used ROUTEPATH to avoid having to type the complete path)

Notice that this call to locateFile has placed </Views/> (the $folder argument) in between
Bobk\ and airports. This is obviously an incorrect path and results in
ViewException:
Invalid file: Bobk\airports\views\moduleTest.php

Note:
locateFile() returns false if it can't locate the view file, NOT the offending path which
is probably why the invalid file displayed on screen doesn't match.

WHAT APPEARS TO WORK (but for how long ?)
Edit system/View/View.php LINE:197 and replace 'Views' argument with an empty string ''

Code:
197 $this->renderVars['file'] = $this->loader->locateFile($this->renderVars['view'], '', empty($fileExt) ? 'php' : $fileExt);

Not advocating this as a real fix but haven't yet managed to find out why the
'Views' argument is there and what it is meant
to achieve. Testing this modification with modules and with normal app controllers
and views works.
Must be a reason for 'Views' argument and I look forward to finding out from those
wiser (more informed) than me.
