I have also tried this.
I suggest you to try the below troubleshooting steps and check:
Press CTRL+Shift+ESC, to open the Task manager.
Click File > Run New Task.
Make sure you have a check mark beside “Create this task with administrative privileges”
Type the following in the Powershell prompt:
$manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + '\AppxManifest.xml'; Add-AppxPackage -DisableDevelopmentMode -Register $manifest
Close the Powershell window
Reboot/Restart the computer.
Didnt work eithier.
