My Sims 4 Files are corrupted?!?

My Sims 4 game has not been working for two years and i can't seem to figure out why. I first noticed the issue when there was no longer the Sims 4 logo on my desktop. Upon visiting the EA app and launching the game from there, the app suggested that there appeared to be a corrupted file on my game and that i could repair it right then and there. After multiple times trying to repair it through the EA app nothing seemed to work. At that point i had tried to repair it nearly 50 times and there was still no success. Every time i try launching the game nothing seemed to get fix and it continued to say that there was a corrupted file. I figured that the game its self was the problem and i should try reinstalling it instead. After going as far as uninstalling and reinstalling the EA app and the Sims 4 all together not was still no solution. There is now no longer a Sims 4 shortcut on my desktop and each time i reinstall the game it appears as a file/folder that i can't access. I have now lost all patience and no longer know what to do. Please help!!!
