Cannot unlock "Macintosh HD - Data" disk

Edit: I actually deleted my hard drive and preformed a clean install of MacOS Big Sur when the MacBook repaired.

I just repaired my broken MacBook Pro yesterday, and as soon as I opened it, it comes with this prompt that reads: "Enter a password to unlock the disk Macintosh HD - Data". I tried entering my user login password and my iCloud (Apple ID) password. But none worked. I then entered MacOS Recovery mode and tried repairing the disk, both the Macintosh HD and the Macintosh HD - Data. I also have 3 Macintosh HD - Data disks for some odd reason. After I repaired Macintosh HD, I clicked on Macintosh HD - Data, and repaired it. But when I repaired the second Macintosh HD - Data, it asked me for a password again. I just cancelled and the reparation cancelled. So, I exited MacOS Recovery and the same prompt came. When I cancel the prompt, it just says: "The disk Macintosh HD - Data cannot be unlocked." Please help.
