windows lock screen icon become square
I just wake up computer after sleep and then it happen
What should I do to fix this problem?

I have clear spotlight cache and setting via cmd

DEL /F /S /Q /A "%USERPROFILE%/AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets"

DEL /F /S /Q /A "%USERPROFILE%/AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\Settings"

and re-config it at setting -> personalized to picture then spotlight

now it works!

thank you.
