Microsoft Store update keeps stopping on XBOX One

i have the same problem. are you an xbox insider on a preview build? i am and reported it using the report feature. if you are please do the same and just cancel the store update for now. you can report by holding the xbox button in on your controller then
go to report problem.

if you are not on the preview program then i think we need to wait for an update.

This Reddit XBox Insiders post has staff comments addressing this issue that started two
updates (2 days) ago with ASA and Alpha preview rings.

Are you in a different Insider preview ring or General Availability OS?

It's a known issue, Microsoft are working on it. The store will still work as normal, you just won't have the latest version.

-Log out and sign back in

-Perform a hard reset and power cycle your console. Hold down the power button on the console for 10 seconds while it shuts down. Then remove the power cable from the outlet for about 5 minutes. Then re-connect everything
and boot back up.
