Unable to open the game

I am unable to open my Sims 4 game. Each time I try to launch it, I receive an error code message saying im unable to start the game and that a specific piece of  CC is preventing the game from starting. When I delete that CC, another piece of CC causes the same issue, even though it has never been a problem before. This situation occurs with every folder in my game. I've used mod manager to delete all duplicate CC and remove any conflicting mods, yet my game still won't open. I have repaired the game, uninstalled it, and reinstalled it. I also tried the 50/50 method, but it didn't work. The only way I can launch my game is without any mods. Also I don’t have any gameplay mods downloaded.
