Sims 4 Crashing

Update: I tried the 50/50 method with all my other cc and couldn't reproduce the crash.  Thought I was good to go since it seemed to stop crashing.  Then it crashed again.  I don't know what to do at this point.

staaby16​  Sometimes the problem mod is dependent on a different mod in order to work, and if the bad mod and the one it requires are in opposite groups, each half will work fine on its own.  To find the problem, you'd need to use the classic 50/50 method twice: put half in, and if they're fine, add half the others while keeping the first half in place.  If the game stops working, you subtract half of the ones you just added, and so on, until you isolate one of the two files you're looking for.  Then you do the 50/50 method again with that one mod in place, testing everything else against it.

The crashes in your dxdiag are too generic to be much help on their own, but one cause of this type (access violation) is a bad mod.  So please retest your mods and cc as described above.

It's also a good idea to update the Nvidia graphics driver, which is from 2023.  Here's the newest one:

Run the installer as an admin: right-click the download and select "Run as administrator."  Restart your computer afterwards and before trying to play.

Thank you so much for the response.  I did end up updating my graphics drivers and I thought that solved the problem, but it crashed again.  I do think it's mod or cc related, but I can't reproduce the crashes as they happen totally randomly (not after doing certain activities or after so many sim days or anything).  I just am not sure how to test since it doesn't crash at the same place every time.  I removed most of my build cc as I can live without it and put my crash report in chat gpt.  It gave me some further suggestions based off of certain cc I had that was high poly, etc.  So I'm going to try removing some of it's suggestions and hopefully it will stop crashing.  I have no problem paring down my cc, I just have no idea where to even start looking for the issue.  Thank you for the help though!

Broken and Updated Sims 4 Mods and CC: 1.117, Aug 19, 2025 Game Update | EA Forums - 12473785

Luthienrising has one such list for each major patch.  If you don't want to read through the entire thread, scroll down and load the whole thing at once, then use ctrl-F to search.

Scarlet's Realm has a longer list (multiple lists, actually) of broken mods and cc, but the site can't be linked here because it contains adult content.  You might find it useful though.
