@d.garding - vielleicht hilft diese Fehlermeldung weiter (hatte ich Heute bei der Aktualisierung auf 5.0.2 bei einem Shopware 5.6.10 Shop - danach war sogar das Frontend weg („Ups ein Fehler ist aufgetreten“) - bei Shops, nur das klassische PayPal aktiv hatten (und kein Express oder Ratenkauf) ist der Fehler nicht aufgetreten.
Bei dem betroffenen Shop habe ich „Warenkorb übertragen“ bei allen PayPal Varianten deaktiviert (in-Context Modus ist weiter aktiv) - danach ging die Seite wieder.
