Windows 10: Fehler 0xC004C003

Hallo, Ich habe meinen PC neu aufgesetzt und wollte wie vorher windows 11 pro aktivieren mit meinem Key. Habe immer den Fehler 0xC004C003 und kann den Key nicht aktivieren bzw. Windows. Habe beim neu aufsetzen eine neue ssd benutzt, liegt es daran? Ist der Key sobald man den auf einer Festplatte hatte "verbraucht" ?
