The game starts but does not work (Assassin's Creed: Valhalla)

An interesting thing turns out ..
Pirate game version 1.2. (1.6 is not hacked) and so on Win 11 assembly 2000 did not start, but only on version DEV, updated Windows to assembly 22621.674. The game started, played a little, and then just stopped working, that is, it starts, but when you choose to continue or a new game, it crashes.
Tell me what it could be and how to solve the problem?
