When I open the Windows Store app, it immediately closes. Event Viewer says this: "Activation of the app Microsoft.WindowsStore_8wekyb3d8bbwe!App for the Windows.Launch contract was blocked with error 0x80073CFC because its package is in state: Error from application of unknown origin." The Store in the All Apps screen displays an icon, but if I pin it to the Start menu, it has no icon. I tried to use the PowerShell to remove it, but I get an error:

System File Checker did not detect any corrupt files relating to Windows Store. It did detect my graphics drivers as corrupt, which is a false flag. Can anyone help?
