Probleme lancement bootcamp

[Mrg91]

Bonjour à tous !

Alors je m'explique hier j'ai utiliser l'assistant bootcamp afin d'installer windows sur mon macbook pro sur big sur, installation qui s'est déroulé sans probleme. Mais voyant que j'ai alloué peu d'espace j'ai décider de supprimer cette partition (avec l'assistant bootcamp) et de l'installer une nouvelle fois en allouant 400gb.

Sauf que depuis il m'est impossible d'installer en utilisant bootcamp car lors du partionnement le message : "Votre disque n'a pas pu être partionné" apparait

diskutil list:
