My Xbox S storage went from 76% to 99% AFTER deleting games…

Well today's the big day. After this post I will begin copying over everything on my Xbox to an external drive. Profile, settings, data, apps, games, ect. Then I will turn off my Xbox, disconnect the drive (to be certain I don't delete it's data) 1st remove
Fallout 76 and data from my Xbox (not the cloud) then my profile. 2nd perform a proper hard reset. 3rd re-add my profile then Fallout 76. 4th test it out 🤞 I will be back after everything is complete to give an update on how things went.

Also I know this version is 99$ right now but at the time it was on sale for around 76$ and after tax it was 86$

So I went ahead and deleting the Cloud Storage Cache on my Xbox Hard Drive. Then I went to storage options and my Cloud Saved Games option in the Storage Devices screen said Cloud Storage was ready to be configured. When I clicked into that option it said
my Cloud Storage was currently disabled and my options were to enable it and disable it. I went ahead and enabled it, the screen looked like it loaded something, and then went back to my Storage Devices screen where it showed Cloud Saved Games to still have
the option of "Move or delete only". Thank you for the recommendation, Hassassinade.

Tried Darren's instructions with collection 1, which I bought previously. It appeared to my active downloads and it downloaded that 108kb size file. After that I went into MW3 and tried to download those maps again. Same problem as before, in game this same
error message and after coming back to xbox home screen it downloads to 99%, then shifts back and forth between 0% and 99% and eventually says that "unable to download.."

Also that 108kb file appears only 56kb in the storage menu, so no change at all.

I believe I may have found out where the issue is coming from. I went to Settings on the Dashboard. After that System. Then I went to Storage. I entered into the Hard Drive I'm using. Went into System Items. Then I noticed that a few of the system items
were from much earlier dates. So I deleted all of the older files besides the Cloud Storage Cache, Microphone Calibration Data, & the Xbox improvement program Data. After I deleted all the other files besides those three. My issue has been fixed. All the files
I erased were recreated from fresh data. Let me know if this works for everyone else.
