[2021] [Download/Installation]I can't launch the game for no reason

I have a problem since this afternoon, the game gives me an error message (see 1), so I choose the game file, then I check it, fix it, but at the end it gives me another error message (see 2). I then reinstalled ubisoft connect, the game..., but after reinstalling it, I get the 2nd error message, and if I launch the game, and select the right file, I get the last error message (see 3).
After re-installing, I can't verify the file, so the installing game is not recognize like the game
Thank you in advance for your help
