Failed to launch error when using CC

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.
