Game not Launching from EA app after Update.

@LittlePinkDino16  If you use a third-party antivirus, please set exceptions for TS4_x64, TS4_DX9_x64, and TS4_Launcher_x64; or the entire Bin folder they're in.  You may need to repair the game afterwards.

If that doesn't help, please run a dxdiag and attach it to a post.

Thank you! So I tried to run exclusions on my antivirus and they didn't seem to help.

I've attached the dxdiag.

I also found that the Sims 2 won't launch but Plants vs. Zombies will.

@LittlePinkDino16  Your dxdiag lists a few generic Windows update errors, and it's a good idea to clean those up.  So please run a couple of basic checks of your Windows system files:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes, and enter
• The system will start validating soon. If it throws an error, please list it here
• After it reaches 100%, hit Windows key-X again
• Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes, and enter
• Post the message you receive here

Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates.  If any install, restart again afterwards.

The dxdiag does not list any Sims 4 crashes, or any errors that might plausibly prevent the game from opening.  That could be because newer errors crowded them out, so please try again to launch the game and then check the Reliability Monitor.  Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day.  Today is on the right.

Look for an error that happened at exactly the time of this most recent attempt to launch Sims 4.  If you find one, double-click it to see more details, then copy that info and paste it into a reply here.  If you don't see a new error, check back in an hour or so—the Reliability Monitor doesn't always update right away.

If you still don't find an error, that means the game is likely being blocked from loading rather than crashing.  In that case, the next step would be to (temporarily) disable your antivirus, clear the EA App's cache:

repair Sims 4, and try to play without the antivirus running.  As long as you don't do anything else at the same time, your computer should be safe.

If that doesn't help either, try playing in a new admin Windows account, as a test.  Make it local, as in, don't link it to your Microsoft account.  You'll be able to (try to) launch Sims 4 without reinstalling anything, but your saves and other user data won't be available.
