Last crash I need help please!!

I apologize if this is a long explanation but I do use mods and cc, I figured it was one of the two if not both so I took out all the object cc I wasn’t using yesterday which happened to make my game run a lot smoother but about an hour and a half in it crashed. I repaired my game and I tried to update all my mods that needed updating so I figured it was the cc mostly. The crashing all seems to happen at different times, the past four times, the first time I was trying to put a lot from the gallery down and it kept crashing during that process so I ended up using a different lot which happened to work bc I figured that other one was bugged. Then on the lot I put down I was trying to copy and paste a tray sim to another sim and it crashed while doing that but when I tried again it was fine. The last time BEFORE I took out a bunch of cc, my sim was going to bed and it crashed it kind of lagged before she got in bc the time speeds up when everyone is sleeping and it crashed. Then AFTER I removed some cc it ran very smoothly for about an hour and a half and it crashed right after I asked my toddler to put in her hearing aids using the BG Health System I believe. From all the crashing I did try to play a vanilla game and it completely worked fine nothing happened so I know it’s something in my mods folder, I just don’t know what. Using the 50/50 method would take a long time bc I don’t necessarily know what’s causing crashes bc what part crashed before usually doesn’t crash again “except me trying to put down that first lot”. Like all the things that was happening while it crashed I did end up trying to do again and it worked so that’s what’s makes it difficult. I’m willing to take out what I need to get my game to run better.
