modded ts4 repeatedly crashing my laptop since last year :(

hi everyone! since last november, my sims 4 game has been freezing at random moments, then crashing my entire laptop. just today, it has crashed 6 times. it also takes forever to load in.

i've repeatedly updated my mods/cc. i've 50/50'ed my folder. i've organized everything with the help of mod manager. i've done batch fixes. i've taken out everything except for what i need for my save.

when i remove my mods folder, the game loads quickly, but i don't play it long enough to see if it crashes. i definitely suspect it's some cc, but when i put it back and 50/50, nothing happens? i'm so confused.

does anyone have any suggestions on how to finally figure out what's going on?
