\DeclareNameAlias{labelname}{default}

hinzufügen.
Am besten direkt nach dem \DeclareNameAlias{sortname}{default}.

Wenn ich dies in OVerleaf teste, wird leider über den Style: 'ext-authoryear' und 'innamebeforetitle' gemeckert. Wenn ich die Zeilen herausnehme, geht es weiter bei den nächsten Punkten z.B. mit der Zeile: \DeclareDelimAlias (undefined control sequence.

Hat jemand eine Idee?

Danke!
