Hello Varish Mirchandani,
Thank you for posting in Microsoft Community.
Based on your description, you are playing Starfield and is unable to sync the saves well. Let us check on this together and sort this out in timely manner.
Starfield is part of Play Anywhere and should allow you to save your game from different platform. The inability to sync a previous save of the game usually happens when your internet connection is unstable the game was not connected to Xbox Network for syncing, or your console enabled offline gaming. For this issue, we would like to ask for few questions:
May we know if you have issues playing other play anywhere game title?
May we ask if you are having issues keeping the saves of other games?
Did you encounter an error message or code?
For troubleshooting we recommend trying the following steps:
1. Make sure that both your Xbox Series X and PC are connected to the internet and that your Xbox Live account is signed in on both devices.
2. Check to see if there are any updates available for Starfield on both your Xbox Series X and PC. If there are updates available, make sure to install them on both devices.
3. EDIT: If none of the above steps work, try signing out of your Xbox Live account on both your Xbox Series X and PC, and then signing back in.
If you continue to experience issues with syncing your saved games, it would be best to report this issue to the game support and with Team Xbox.
