Benutzergruppe kann nicht angelegt werden «Internal Server Error»

[Julia]

Hallo

Ich nutze Contao 4.4, mir ist jetzt aufgefallen, dass wenn ich eine Benutzergruppe anlegen möchte, folgende Fehlermeldung erscheint:

Internal Server Error
Was ist das Problem?
Cannot create references to/from string offsets

Im Log steht folgendes:

Kann mir jemand sagen, was das Problem ist?

Danke und VG, Julia
