I need help with a problem

I was updating warzone and then the blizzard app crashed, but when I launched the blizzard app it said I needed to install warzone again but is still on my pc. I mean by the files.

See if you can hit “Locate my game” below the install button and navigate to the COD folder on your PC.

I did it gave me a error. uninstalling and reinstalling it see if that works

same problem here
