Cannot uninstall the EA APP to reinstall it because i can't launch my games

Hi

I'll cut straight to the chase : i literally cannot uninstall the EA app because the uninstaller isn't existing at all. 

I wanted to uninstall the app because it wouldn't let me launch the EA games i bought on steam, so now i'm stuck with a worthless app and unplayable games

any known fix to this issue ? 

EDIT : already tried downloading the EA app again to use the "repair" option but it doesn't work either (i get an error message)
