Mmmh I don't think it's that. Same happened to me and I didn't copypaste anything. Had the file backed up and still didn't work after replacing with backup. Deleted file, verified steam files, reacquired it, still had the same issue. Had to redownload the game and it worked just fine. Also, some crashes on load are!! due to graphic drivers issues (nvidia 1080 here), try reinstalling them first to see if it works, its faster to do.
