Setting baseURL in Registrar not working

Unable to reproduce your error, here is a live example.

The code for app/Config/Registrar.php

PHP Code:

<?php

namespace App\Config;

class Registrar
{
    public static function Database(): array
    {
        return [
            'default' => [
                'database' => 'default.db',
                'DBDriver' => 'SQLite3',
            ],
        ];
    }

    public static function App(): array
    {
        return [
            'baseURL' => match(ENVIRONMENT) {
                'staging' => 'http://mydomain.com/',
                default => 'http://192.168.0.1:81/',
            },
            'indexPage' => '',
            'appTimezone' => 'America/New_York',
        ];
    }
}
