Game crashing after 10 mins of gameplay

@Emiii20078  Thanks for the dxdiag, but it's missing what would typically be the most useful information: the Windows error reports at the end.  Do you use some kind of cleaner app that deletes temporary files?  If so, please disable it while troubleshooting here—we don't want it deleting Windows crash logs or anything else potentially relevant.

As an experiment, please try playing with your computer 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.

If this doesn't help, 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, specifically while offline.  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.

The lastcrash file wouldn't help me here anyway.  While Maxis people likely can read them, I can't, so don't worry about attaching one.

@Emiii20078  The faulting module here, ntdll.dll, is such a fundamental part of Windows, that if it were corrupt in any way, you would probably not be able to use your computer at all.  So the problem is likely something calling it incorrectly.  That, unfortunately, still leaves a lot of possibilities.

Please test online but with no mods or custom content at all, and let me know whether this exact error happens.  If the game runs fine, that's your answer.

If you get another crash but a different error, please post the RM info here.

If you get this exact error again, while playing online, let me know what antivirus you use.  Please also test with the EA App in offline mode but your computer still online.

@Emiii20078  Please try playing in a clean user folder.  Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop; if the folder copies instead of moving, or you get an error when trying to move it, stop here and let me know.

Otherwise, when you launch the game, if it launches, a clean folder will spawn with no content.  (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.)  Don't add anything to the new folder yet; just let me know whether you can get far enough to start a new save and play in live mode for a bit.

@Emiii20078  Rather than adding back your custom content all at once, test it to see what's causing the crash.  The 50/50 method can make the process more efficient:

When you've finished sorting through the contents of your Mods folder, you can add back the contents of the saves and Tray folders, plus Screenshots and Recorded Videos if you care about those.  The other files are extraneous and can be discarded.

@Emiii20078 Have you looked at known broken items in Broken/Updated Mods & CC , including "previously broken"?

For finding conficting CC, you can use an additive test method, adding in batches. But also, when you do a 50-50, are you ensuring that mods have the other mods they depend on? See the instructions here: 50-50 (some online instructions miss this aspect of testing).

@luthienrisingI have looked through the broken/updated mods forum and nothing in there is the issue. can you please explain the additive test? or am I overthinking and it's simply just adding stuff in?

I wanted to add does cc also have items it depends on? I'm trying to think if I accidentally deleted some kind of mesh but would that really cause big issues?
