Unspecified error (Excep_FromHResult 0x800004005) (0x800004005) windows 10 xbox insider hub

Open PowerShell as Admin and type this command in and problem solved here! Thanks so much!

Get-AppxPackage -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

Ok so I originally removed the store from windows, I did this to re install it:

Get-AppxPackage windowsstore | Remove-AppxPackage

Get-AppxPackage xboxapp | Remove-AppxPackage

Get-AppxPackage -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

Then I upgraded to Windows 10 Fall Creators and now everything works fine.
