Sims 3 Wont Open After Hitting Play

enei7eb5nb9w  You definitely need(ed) the Alder Lake patch or another intervention, but your dxdiag doesn't list any Sims 3-related errors.  That means the game is likely being blocked from opening rather than crashing.  So as a test of a number of possible causes at once, please try playing in a new admin Windows account.  Make it local, as in, don't link it to your Microsoft account or any email address.  You'll be able to open Steam and try to launch Sims 3 without reinstalling anything.

If this works, quit the game, restart your computer, and try again, to make sure the game still opens.  Let me know the results regardless, and we can go from there.  The game working in the new account (more than the one time) means the issue is limited to your main account, and either way, we know where to look next.

If you still can't open Sims 3, please look for new errors in 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 your most recent attempt to open the game.  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.
