Sims2 Pink flashing persists how do i fix??

I have sims 2 ultimate collection. I did GRM, Rpc, DXVK, nothing seems to be helping the issue. Any suggestions?? I also have a lot of cc 4t2 conversions I know this is considered high poly custom content should I downsize will this help the flashing??

Hey, I am not an expert by any means, so just in the meantime until someone else will answer you, here's my assumption.
Two things:
It looks to me like your graphics rule maker is forcing the game's Texture Memory to a level that is higher than what you actually have.
GRM: Force texture memory: 4096 Mb
Yours: display memory vram 1995mb
Since I've read that pink flashing is mainly a matter of texture memory (rocket horse gave an explanation in this posts most bottom comment), maybe try to remove that option from GRM and set it yourself?
I used Kiri's tutorial - Here.

Secondly, about your first sentence, to my understanding - Texture size is what's clogging the Texture Memory (Reference), so i'd suggest opening your 4t2 cc on SimPE and see what needs to be downsized. Another tip is on Rocket-Horse's post I linked above.
Good luck.
