Sims 4 Toddler & Vampire keeps crashing

Hi there!

I just installed the alternative toddler & vampire method, I deleted and backedup my files from my Documents for the old Sims 4 files. However, I did copy my mods back to the newer Sims 4 folder. Could this be the reason why I keep experiencing the game crashes? My first attempt crashed when I was in CAS, I trying to create and add a new family member. I attempted CAS once again after and I got to choose a lot and played for about 5 mins before it crashes again.

Any help or tips would be appreciated guys. Cheers!
