Mi unlock says Device unlocked, but it is not

[LEV735]

Hi,

i'm bought the Redmi note 7 (global) and applied for unlocking, waited the time, and today i wanted to unlock my bootloader.
It said unknown error -1 several time. Then once it kept saying your device is unlocked, no need to repeat. But it is not unlocked.

What can i do now? I'm afraid the system is marked my phone unlocked at the miui's servers, but it did not unlocked my phone actually, and i can never unlock this phone. (fastboot say unlock false, i'm 100% sure it is not unlocked)

I really want to install twrp, xiaomi.eu with magisk, and now i'm very disappointed
I created a post to mi.com too, but no answer yet so i'm trying here too, maybe someone can help me here

Solved, it was because of my Ryzen PC (r7 2700x)
Seems to be too new lol. I tried with my 10years old laptop and unlocked without any problem.
