Does not start (NieR: Automata)

A very long time has passed it but never finished because my fucking hands I decided to look into incentive cool guide, and I found how to change the character of 2A, then I under download the game(that is, in the main menu when pressing continue) just hangs and closes, the changes made to the registry, but after changing back to 2B, nothing has changed, anyone have the option how to solve?
