Failed to launch error/Fully Black Screen when using CC

for me it needs 4 or 5 or sometimes even more tries until it eventually loads... a bit annoying ngl. I just brute force it for now, eventually after I try to start it multiple times, it starts. to hell with taking out my CC. Its throughly cleaned and fully up to date, as I did some extensive trouble shooting due to another bug I had.

Yeah I've had the same problems and I'm just saying, if I can't use my cc (some of which i've paid the creator for) I will never touch this game again and will uninstall it. It only stopped opening after the most recent update and I am not happy.

I successfully got my game to launch with a whole 195 GB of both CC and script mods (minus my UI mods). So I don't think it has anything to do with mods folder size. I don't think any particular mods are conflicting either. What worked for me was a brute force method. I turned the EA app into offline mode, before forcibly closing it and the EA Background Service through my task manager. I then deleted my localthumbcache and Resource.cfg. And ran the TS4_x64.exe as administrator. It would still crash sometimes, but I'd just make sure to repeat the above steps and try again. It usually worked on the 1st or 2nd attempt, and I was able to fully launch and play the game in multiple instances with all of my mods & CC. No clue what step of that actually allowed me to launch, but some part of it did. Idk if this will work for anyone else, but hopefully it'll help someone. Best of luck y'all.

So that didn’t work for me  I think it’s just an internal issue

What do you mean? Are saying taking out the Ts4script file. I’m not following. 

I have done just want they said and it still fails. 

Unfortunately, that's not it either. My entire Buy/Build CC is in merged files. If I start with just this folder, there's no problem.

I am also experiencing the same issue. I play The Sims 4 on Steam. I have tried all the suggested solutions, but the game still will not launch.

In addition, the EA app frequently fails to connect to the server, and I sometimes receive a “Application request timed out” error on Steam. When this happens, neither clearing/deleting the Mods folder nor repairing the EA app resolves the issue.

I moved each MOD folder out and back in one by one. It worked once, but now it fails 4 out of 5 times and takes over 10 minutes to load. The issue is clearly getting worse, not better. It’s frustrating that EA still hasn't addressed this.

And that update will break something else.
