Hi,
If you have already tried basic troubleshooting, including resetting the Microsoft Store cache, but the issue persists, please try uninstalling and reinstalling the Microsoft Store.
Press Windows Key + X and choose Windows PowerShell (Admin). Copy and paste the command below and hit Enter.
Get-AppxPackage -Name "Microsoft.WindowsStore" | Remove-AppxPackage
Note: Please complete the process before proceeding.
After that, reinstall the Windows Store. Press Windows Key + X and choose Windows PowerShell (Admin). Copy and paste the command below, then hit Enter.
Get-AppxPackage -allusers Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Wait 2 minutes, then reboot your computer and try again.
If that fails, the next step is to try System Recovery without deleting your files and apps.
Click the Start menu > Settings > System > Recovery.
Choose Reinstall Now under the section labeled 'Fix problems using Windows Update.'
Once completed, your system will restart. Please check afterward.
