Trouble with unlocking bootloader

Hello, I need help to unlock my bootloader on Redmi Note 12 Pro 5G, I have had an active account on the Mi community for 400 days and I requested an unlock which was accepted until 2025, I waited 7 days but when I try to add my account in the developer options, a toast appears: "Your account is not authorized to unlock, please change another". I have only unlocked 2 devices with this account.

I also tried with another account more than a month old, this time it works but it's on the Mi Unlock software that I receive the same error.

PS : Sorry for my english , it's not my native langage
