Problem solved.

XAMPP does not automatically look for /public like Heroku seems to do.

Add your /public folder in httpd-vhosts.conf

<VirtualHost *:80>
    DocumentRoot "C:\xampp\htdocs\ARCADIA-2025-LASTRUN/public"
    ServerName ARCADIA-2025-LASTRUN.local
    <Directory "C:/xampp/htdocs/ARCADIA-2025-LASTRUN/public">
        Options -Indexes
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>
