Problem nach Update auf Shopware 6.5.6.1

Hallo zusammen,

ich habe heute ein Update von 6.4.20 auf 6.5.6.1 versucht und bin im update Prozess mit einem Fehler konfrontiert worden. Danach hab ich das update erneut gestartet und es ist durchgelaufen. Seither funktioniert weder Front-End noch Back-End „500 Internal Server Error“
