How debug Tutorial - News section to pass "We seem to have hit a snag. ..."

Hello,
i'm at very first attempt to use PHP and CodeIgniter4 . I have installed Apache2.4 and PHP7.2.22 and set SQLServer on Windows10 and test them all together using this code:
<?php
$serverName = "MyPCName\\sqlexpress, 49172"; //(default port is 1433)
$connectionInfo = array( "Database"=>"News4CodeIgniter", "UID"=>"sa", "PWD"=>"MyPassword");
$conn = sqlsrv_connect( $serverName, $connectionInfo);

if( $conn ) {
    echo "Connection established.<br />";
}else{
    echo "Connection could not be established.<br />";
    die( print_r( sqlsrv_errors(), true));
} 

?>

So far so good, I have seen: "Connection established" on my browser.

Now I installed CI4 using Composer:
composer create-project codeigniter4/appstarter newsapp -s rc
then:
composer update
and follow all the steps from Tutorial - Static Pages with success, then News Section where I hit the problem of debugging because I obtained just an very unfriendly message: Woops! We seem to have hit a snag. Please try again later...

I had already set into app\Config\Database.php the database $default variable with:
public $default = [
'DSN'      => '',
'hostname' => 'MyPCName\\sqlexpress',
'username' => 'sa',
'password' => 'MyPassword',
'database' => 'News4CodeIgniter',
'DBDriver' => 'sqlsrv',
'DBPrefix' => '',
'pConnect' => false,
'DBDebug'  => (ENVIRONMENT !== 'production'),
'cacheOn'  => false,
'cacheDir' => '',
'charset'  => 'utf8',
'DBCollat' => 'utf8_general_ci',
'swapPre'  => '',
'encrypt'  => false,
'compress' => false,
'strictOn' => false,
'failover' => [],
'port'    => 49172,
];  


Now I'm stucked, I don't know what is happened backstage and I don't know how start debugging, where to set something and where to look for seen what is happening, why I cannot move forward.

I found into the root of my application folder the file named: env and changed the line:
#CI_ENVIRONMENT = production 
into:
CI_ENVIRONMENT = development

and restart the server with the command: 
php spark serve 
from command line . 

Starting again the application with: http://localhost:8080/news and hit again the same cryptic message:[url=http://localhost:8080/news][/url]
Woops! We seem to have hit a snag. Please try again later...

Please explain or point an tutorial for debugging for newbies, I chose CodeIgniter4 and already invest few days of work to achieve theese, now I want to move forward but I cannot without external help. Thank you in advance.
