After healing Atreus' T-pose, enemies began to die on their own (God of War (2018))

Such a problem, I used the fling trainer and when I was testing the surtra in muspelheim, I clicked on instant kill, after the atrey broke. Well, after reading the forums, I found a solution to the problem through cheat-engine, did everything according to the instructions, Atrey sagged. After all "this" I again went to pass the tests, but found that almost all enemies die at once, and some are "immortal" and they can only be finished off, and Kratos himself with half HP does not die either. In short, who faced and how to solve the problem? help me please
