Sims 4 won't run after updating to Windows 11

kikibay  I've split your post into its own thread because it's easier (for me) to troubleshoot with one person per thread at a time.

What happens when you try to play?  Please describe what you see, and include a screenshot of any error message that appears.

Please also try playing in DirectX 11 mode.  If you've specified DX9 mode in the EA App, remove -dx9 from the command line box under Sims 4 > Manage > View properties.  If you've chosen DX9 mode in the graphics options, uncheck the box, unless you can't get that far, in which case open Documents > Electronic Arts > The Sims 4 and delete Options.ini.

If you still can't play, 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 Sims 4 crash.  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.
