black stripes on sim

i havent played sims since august 2025. and since last week ive been trying to debug the game. firstly it would keep looping the world i somehow fixed that and now theres this i cant seem to fix it. i know that its a CC issue. i did 50/50 several times, deleted the cache, updated CC's but it isnt working. Also the sim is perfectly fine in CAS. i tried taking everything off my sim but it was still covered in black patches. if anyone know how to fix this or the possible list of CC that could be causing this please let me know. thankyou
