All of a sudden, my saved games have disappeared from the in-game LOAD and SAVE menus. The "Autosave" file is the only option that shows up in the UI.
More frustratingly, new saved games don't show up either. So, I can't even continue playing and saving progress.
I have tried starting a new game and saving, but it didn't make a difference.
I am playing on Xbox Game Pass for PC.
