phpdesktop laravel blank white page

i need to make a website available offline, right off the bat my idea is to create a desktop app that would sync the database when connected to the server, then i came across phpdesktop, just tried using it for my brand new laravel project, but for some reason when i run the exe the only thing showed up is a blank white page. what seems to be the problem? the project is brand new

the settings.json web_server is edited according to tutorials online :

{
    "web_server": {
        "listen_on": ["127.0.0.1", 0],
        "www_directory": "www/public",
        "index_files": ["index.php"],
        "cgi_interpreter": "php/php-cgi.exe",
        "cgi_extensions": ["php"],
        "cgi_temp_dir": "",
        "404_handler": "/index.php",
        "hide_files": []
    },
    "chrome": {
        "log_file": "debug.log",
        "log_severity": "default",
        "cache_path": "webcache",
        "external_drag": true,
        "external_navigation": true,
        "reload_page_F5": true,
        "devtools_F12": true,
        "remote_debugging_port": 0,
        "command_line_switches": {},
        "enable_downloads": true,
        "context_menu": {
            "enable_menu": true,
            "navigation": true,
            "print": true,
            "view_source": true,
            "open_in_external_browser": true,
            "devtools": true
        }
    }
}

log that comes out:

Just update php from 7.1 to 7.2.19. I find this repo https://github.com/laravelarticle/laravel-desktop and notice that this working on higher php.
