Issue while updating to 11.6

Hello,

issue while updating :

after updating WEG, Lilu and AppleAlC, at reboot, stucked on white logo Apple.

No recovery mode is working neither selecting HDD (Mac OS or Mac HDD)

Booting with USB Big Sur Key is no working too.

Booting with USB for linux distro is working fine.

Any idea, advice ?

PS : using OC073 and OC074.

Many thanks.
