Switching from pirated to purchased (Forza Horizon 5)

Good day! The question is that I used to play FH5 on a pirate with an online fix, I played enough time, but then, after the next update, the game stopped running at all. I decided to buy an activation for the MS Store, after which I got Xbox Game Pass Ult in xbox. I downloaded the game, and there seemed to be no signs of trouble, but when I started the game, it started from the very beginning. Although in the Xbox profile, I have all the achievements that I received earlier. Tell me what to do and how to transfer saves?
