Game Failing to Launch

I’ve been trying to fix this problem for days now. I have removed all my mods, repaired the game, created a new folder for the sims, uninstalled and reinstalled, I’ve done everything recommended. Every time I try to add just cc back into the game, I keep getting an error that says “Failed to launch game. An error occurred on our end that caused the launch to fail. Try again a little later”. I have tried later, the only way I can get it to work is if I remove all of my cc. I’ve tried putting in little by little and for the past few days I have literally been going through each piece of cc to find what’s broken. But then the next day, or even if I take a break and come back, cc that I had previously cleared and could get the game to launch with suddenly doesn’t work. Literally what is happening???
