sonic and the black knight 7z corrupt

Hello! I'm posting this message because I tried downloading Sonic and the Black Knight for the Wii (https://vimm.net/vault/18124), both as wbfs and rvz. The download was completed both times, and both times when I tried to extract in an empty folder I received the error:
"! (game folder)\ Sonic and the Black Knight (USA) (En,Ja,Fr,De,Es,It) (1).7z: Checksum error in (game folder)\Sonic and the Black Knight (USA) (En,Ja,Fr,De,Es,It).wbfs. The file is corrupt"

Windows defender didn't notify me nor does it show anything in the history, and I tried extracting even with the real time protection disabled and still got the error. Only the text file extracts fine. I used WinRar to extract. I have no other antivirus installed.
