" We can't save more data for this game or app " with no solution, what do I do without...

Hi Kellen! I'll do my best to help.

It seems like your games' local data are corrupted. It would be best if we clear your local saves. Don't worry, your game's data or progressions are synchronized through the cloud and will be re-downloaded once you sign in and get into the game:
Press the Xbox button to open the guide.
Select Profile & system > Settings > System > Storage devices.
Select Clear local saved games.
Note: Selecting this option will not delete any games or progress you have saved in the Xbox cloud. It will only clear data you have saved locally.
Select Yes to confirm.

Let me know if that works.

Best regards,

Hope you're doing great today mate

May I know if you tried deleting some cloud data from another games to see if that makes the trick?

Also, is this happening with all your games?

Or only with the ones you described ?

Hello, i have tried that option too (reset and keep all my games)

I have enough space on my internal and external totalling 1.6tb.

Hi iSaoirsexo,

Thank you for posting in Microsoft Xbox Community. I'm sorry to hear that you're having issues with your Xbox. I understand that you are receiving 0x80830003 as the error message and you've tried some troubleshooting steps but none of them worked.

Does this happen to all of your games or just to certain titles? Do you have enough space on both of your internal and external storage? When you performed a factory reset, did you select the "Reset and keep my games and apps" option?

Regards,

Alvaro

you have to delete save Files and choosing the option to do it both locally and in the cloud
