Symphony Exception bei frischer Installation Shopware 6

Shopware 6 (German)
1

Neuen vHost bei Profihost angelegt.
Alles soweit „normal“ konfiguriert.
php8.2
shopware-installer.phar.php ins Hauptverzeichnis

Dann erhalte ich allerdings sowas. (siehe unten)
Was ich bemerke ist, dass in der URL ein zweiter „/“ nach dem Aufruf der URL eingefügt wird.

Eine andere SW6DEV läuft stattdessen mit den gleichen Konfigurationen sauber.

An was könnte es liegen?
