I meet an disk password window when I start my MBP since this morning. I updated it yesterday evening and when I rebooted earlier today, a disk password is asked. I don't know that password and don't know how it came there. Looking on the forum, I seems that I enabled Firevault or something like that but how to solve this issue. I tried that command in terminal diskutil apfs updatePreboot disk2s1 but it reutrnan Error -69572: The Subjetc Volume UUID directory was not foung on the APFS Preboot Volume.
Please help how to unlock this without erase my datas ?
