The primary role of Deployment Image Servicing and Management (DISM), a built-in Windows utility, is to scan and fix faulty files. To fix this error, you’ll need to get a USB/DVD with Windows 10 installed on it. Some users attempted to upgrade via the regular DISM method, but the SXS file was missing.
