There was oine there that seemed successful. You tried it? Delete:
C:\Users\Username\AppData\Local\Packages\Microsoft.MicrosoftEdge_8wekyb3d8bbwe\AC\MicrosoftEdge\User\Default
and log off or reboot.
Otherwise, I read this on the Technet pages:
open a command prompt (Admin)
Copy and paste:
DISM.exe /Online /Cleanup-image/Scanhealth
then, when it has finished:
DISM.exe /Online /Cleanup-image/Restorehealth
