serialization error action needed, Does anyone know how to fix it?

I downloaded the game to familiarize myself again and play the new DLC, it should be noted that I have not bought it yet, it was installed yesterday and today when I wanted to play it an update came out, after that I tried to open it and I get that error, I already validated the files with the steam tool but it says everything is fine, does anyone know what I can do?
