"Sims 4 has stopped working" help?

On July 29, I updated my game with the Ultimate Fix and I saw in the instructions a link for if you wanted to use the Gallery. I followed those instructions and downloaded Origin and everything but the game failed to start up so I decided using the Gallery wasn't that important anyway and uninstalled Origin. The game worked fine after that and I played for hours. The next day, July 30, I decided to download some new custom content to my game. Then I went to start the game, eager to try out my new custom content, but it said "Sims 4 has stopped working" and that windows was searching for a solution. I thought maybe it was the custom content so I took out all of the content that I downloaded that day and tried starting the game again but it still failed. I've tried using the Ultimate Fix again, hoping that would work, but it didn't. I tried again today and it still didn't work. I don't know what I did to make it not work... Is there a way to fix this? Hopefully, without having to uninstall the game completely and then reinstall?

Hey there, 

your Problam could literally be anything.. 

But i have some Ideas you could try before reinstalling:

1.Completely move your mods Folder (maybe something in there is currupt).
2.Complety move/remove your Sims 4-Folder inside your Dokuments/Electronic Arts (if you remove it all you saves/settings will be lost).
If you dont want to risk loosing anything out of these folders you can skip 1+2 and just use a language changer provided with the game installer. (I can upload them somewhere if you want)

Change the Language to a language you didnt allready use and Sims 4 is going to create 100% new configs/saves etc. 

That should reveal any error in your settings/mods/saves.

If you game still crashes after you changed here are some more ideas:
3. look for any artifacts Origin left (old files, maybe even a process that starts on boot).
4. Maybe someone lese in this Forum has an Idea. 


5.reinstall, Sry no other idea  .

Thank you, DarkTJ!
I completed removed the mods folder therefore removing all my cc from the game. How do I find corrupt cc? Like I said in my first post, I removed all the cc I downloaded that day to see if it was something I just downloaded, meaning all the previous cc had worked just fine in my game. But since it worked without any cc that means it has to be something I've already had in my game before?
Edit: I did some sort of process of elimination type thing and found what was preventing my game from starting. Thanks for the help!
