Did you make any major hardware/software changes with your PC recently? Do you have an anti-virus such as Avast? Some anti-virus' love to attack games such as this and then quarantine the files as a false positive. So when you try and start up the game, everything that is needed in the folder was already moved/deleted by your anti-virus. Try disabling your anti-virus and then reinstalling the game.
According to the patch notes, there isn't anything new added in or removed that would have a significant effect on the game. Also trust me, people have eyes like a hawk and look out for things like a madman. If there were an issue like this on Steam or elsewhere for everyone or a majority. I'd have heard about it instantly in the discord servers.
Again and I can't stress this enough; no one but you seems to have this issue. It doesn't have anything to do with the game most likely. If this is still an issue please get back to me here.
