Geralt receives no damage (The Witcher 3: Wild Hunt)

Hello, this problem.
Geralt does not receive damage in battle or gets it in the amount of 0 03, that is, cannot die. Tried to jump off a tall building - the scale of health has not diminished, the enemies quietly attacked, despite the fact that Geralt is lying like a dead man. Console use is very rare, the game is GOTY, version 1.31. Perhaps there are some decisions not to replay the game?
