I recently ran into an issue with Halo Infinite where I was unable to update the game despite clicking repeatedly on the update button and expecting it to queue up but it failed silently. Thankfully the resolution was nice and easy!
In order to resolve this issue, I fired up the Microsoft Store, clicked Libary > Get Updates > Update All after doing this I restarted the Xbox app and Halo was updated (is it’s an app in the store). Presumably, the update depended on updates to the Xbox App, Gaming Services, App Installer, or Microsoft Store as all of those required updates. If I come across this issue I’ll patiently test each item instead so as to narrow down the culprit. Hopefully, this helps if you come across this issue too!
