Hello,

You can reinstall the Microsoft Store by following the steps below; this usually resolves issues where the app won't open or downloads fail:

Right-click the Start menu, select "PowerShell (Admin)," and enter the following commands:

Get-AppxPackage Microsoft.WindowsStore | Remove-AppxPackage

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

Restart your computer after completion, and the Microsoft Store should return to normal operation.
