Guys what antivirus do you have? I had the same problem.. then i figured out that my antivirus (i have quick heal) automatically deleted 2 files from gta 5 folder and 1 from pes 2017 .. it took me four days to find this out lol. You have to check with your antivirus the files that it deleted and restore those files from there then launch the game 👍🏻👍🏻
Also secure those game folders as trusted so your antivirus won't delete it again.
I hope this helps
