Kopie eines Newseintrages bringt Fehler

Hallo,

Contao 4.11.1

Ich kopiere eine Neuigkeit. Die Neuigkeit hat ein Weiterleitungsziel auf 'Individuelle URL' eingerichtet.
Ich wähle ein neues Weiterleitungsziel aus und speichere.
Das Speichern bricht mit Fehler ab

Code:

---

Forbidden
Was ist das Problem?
Cannot load record "tl_news.id=425".

---

Ich kann das Verhalten beim Reproduzieren auf die Auswahl der URL einschränken - sprich, wenn ich das Weiterleitungsziel (welches immer nur intern auf ein anderes Newsarchiv läuft) nicht ändere und speichere, klappt das Speichern.

unter var/logs gibt es keinen Logeintrag.
DebugMode:
Stack Trace 1/2 - AccessDeniedException

Also workaround klappt ein Speichern bevor Änderungen in der URL Auswahl vorgenommen werden.
Die Auswahl der URL erfolgt über den URL-Picker.

Bug?
