Game keeps Crashing...

yanyiz​  Your new dxdiag lists two crashes of a component of the Nvidia graphics driver, so the next step is to do a clean uninstall and reinstall of the driver.  Here's how:

However, instead of reinstalling the newest driver, which has had some issues along with its immediate predecessor, try an older one, maybe 576.52.  You can always update from there, but going from a newer driver to an older one requires using DDU again.

You'll only want Game Ready Drivers, not Studio Drivers, which are for professional workloads.

If you get yet another crash, please look for new errors in the Reliability Monitor.  Click 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.

Please test by creating a new save and choosing a lot in one of the base game worlds.  If that's fine, you can test one of your existing saves.  I don't need a lastcrash if the new save crashes, only the main one—these files are mostly not useful to us (volunteers) but can help when EA is investigating bugs or other sources of error on the game side.
