Sims4 not opening

@ju2jps0ft81x  Is your game working at the moment, and if so, what, if anything, fixed the issue, that is if you know?  Based on the timing, it sounds like the precipitating event might be the patches, but that still leaves a variety of causes, anything from outdated mods to an antivirus blocking the game when the executable changes.

At any rate, let me know whether the game is working, and if not, what antivirus you use and whether you've tested with no mods or custom content.  I would also like to see a dxdiag from your computer; you can attach it to your reply.
