Several users have reported receiving error messages 0x80070520 when trying to change their account profile picture. The error primarily occurs on devices with a local account only, meaning you won't encounter it if you're using a Microsoft account.
The error prevents users from changing their profile picture because Windows 11 can no longer save the image to AppData\Roaming\Microsoft\Windows\AccountPictures.
