Check the Mod List to see if any of your Mods are currently broken or have an update available. As far as CC's best option is to test them all in CAS/BB. I usually go through and put them all on my sim until it creates a bug of some kind, or place them all in a lot until I get an exception alert. It's all fairly simple (albeit time-consuming, depending on how much CC you play with) using Better Exceptions by TwistedMexi. With that mod, you can identify which file it is and delete it (or look for an update/replacement if you're attached to the CC)!
Note: there is a patch coming out today which will probably break some mods/CC so you will need to give it a day or so for the Mod list to update and track those!
