Mobs freeze, problems! (The Witcher 3: Wild Hunt)

I have 2 problems:

1. Some enemies simply do not move, they freeze in place, they can be damaged, but when they supposedly "Die" nothing happens. Here is an example, stuck in a cave, on a barefoot named Nitral (Wild Hunt). Xn I take off and nothing happens, his bar is at 0 and he cannot die, and there is no continuation.

2. Problems with graphics, in some houses, and with some NPCs. I go into a house, and there is just a texture on a texture and there are hundreds of them, they just overlap each other and it’s even impossible to find yourself in them until you feel you leave the house. The second is when there is some kind of NPC, for example, the same magician Keira Metz, who helps me kill the boss. When she is standing, the model is perfect, begins to move, giant rays with opaque textures emanate from her to the very sky, and nothing is visible, sometimes her body disappears and only her legs are visible.

How to solve all this?
