Hi, good day!
Please try the following methods below.
- Disable or uninstall any third-party Antivirus program to prevent it from interfering with enrollment process.
- Please try to run SFC and DISM to check for any system errors and corrupted files. https://support.microsoft.com/windows/using-system-file-checker-in-windows-365e0031-36b1-6031-f804-8fd86e0ef4ca After that, restart your computer
