Xbox cannot find any saved data

First thing to try is to give your console a
power cycle. This can clear up some corrupted system cache that could cause strange issues, such as cloud syncing problems.

More info about cloud sync errors can be found here: https://support.xbox.com/en-US/games/troubleshooting/cloud-storage-sync-error-messages

i have even tried install a new windows 10, but the game still cant launch after sync my data. I switch to another new microsoft account and launch the game with no problem, seems there have some problem on my save data on cloud and when the data load it just cant load into game. i cannot find any method to delete my cloud save

Sadly, it's not working. I log into XBox Live, try to Play Fallout 4, but it can't find any saved game data..

Hi dear , try one way to solve it was to turn the console off and on completely. The rescue file could be there but it is not synchronously transferred from the cloud, it is not clear if the problem you have on the loading of the save itself exactly
what happens at the time of the failure loaded

If your game crashes on a save screen and you need to close it, proceed as follows. Close the game. Turn the console off and on again and it should be online again, if you don't solve it you can try contacting the assistance with online chat or by phone if
the problem is on the console, if you have problems on the server side Capcom (now I don't know exactly how it acts as a system for saving progress and if it does a login on the capcom server and opens a ticket, but it is only to understand where the problem
of saving failure comes from, you can also try using another console and try restoring your own xbox profile, there are various ways to try to get on top of the problem so go also for exclusion
