Game is not loading, it says game cannot load due to damaged or missing files.

I have not had a chance to play since February and finally had some time to play. But after the new patch or update today, I am receiving the error message that the files are damaged or missing, and I must remove mods, and try repairing or reinstalling from origin. I have already tried to repair the game with my add-on packs, and that did not work. I tried uninstalling game from EA app and then reinstalling, and this also didn't help. Then I read somewhere about backing up your data, by making a copy of your files so that you can delete the game and then reinstall. But when I try to make a copy of my saved games, I receive an error that says "unable to copy content, the cloud file provider is not running." Now I am concerned about losing all of my data and don't want to delete anything, but I also don't know how to repair my game. I will also add that I do not have any mods at all in my game, I have not downloaded any mods, the content used is completely original from the game and is not altered in any way.
