Ever since steam updated my Sims 4 installation yesterday I have been unable to load the game, and instead get the above error message. I have tried to follow all the things other people have done, including doing a clean windows install on my laptop, with nothing else on it at all, and just reinstalled steam and then Sims and the EA app, and still the same result. I tried raising a ticket in the EA app, but nobody ever responded to it 😠
Search for your "controlled folder access" and turn it off!! It's in Windows Security under Ransomware protection. This is the only thing that worked for me after hours of trying everything!
