I really need help

I played forza horizon 4 on xbox with xbox game pass. And the game pass ended. So if i buy a game on pc with same account do i need to start over or can i continue with my data.

Only support can confirm it but since you will log with the same ID, then same xbox profile, the fact that you have pass or not should not come into picture here.

I believe you can continue. There’s one way to find out.

you can continue if it is the same account.
