I installed master chief collection and reach on game-pass PC. I go in game and start reach campaign, open achievements and every single one is locked and has locked icon (prob intentional never played on Xbox before) But even when I complete a task to get an achievement ( any task) none of them never unlock…
Running on latest windows 10 version and playing reach from Xbox app (game pass)
Running the right master chief collection file and not the anti cheat disabled one.
I must add that I can get achievements from other games in gamepass. So the problem is only in Halo
