The testicles are gone !!!!!!!!!! (The Witcher 3: Wild Hunt)

Hello, help please! I downloaded the blood and wine DLC, I was delighted and thought to start playing, I go into the game and textures with just one polygon, while Geralt is in ammunition and everything is fine with him, as well as with the road, and with the inhabitants. I checked it, optimized it through Nvidia, checked the settings in the game, but nothing helps. It became simply unrealistic to play. Help!
