Re: The Sims 4 crashing after 6/6/24 update
@Sbcider Your dxdiag lists crashes of Dell's Alienware Command Center and a component of Killer's networking software, but nothing from Sims 4. So please try playing with ACC shut down in the Task Manager (make sure it doesn't restart itself; if it does, uninstall it entirely, temporarily), and while your computer is offline. You can sign into the EA App and put it in offline mode, then disable wifi and/or disconnect the ethernet cable before pressing Play.
I realize neither of these is an ideal workaround, but they're useful tests. If Sims 4 still crashes, 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 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.
