Based on the information you have provided, considering that creating a new user account did not resolve the issue, then it's possible that the issue is with the operating system itself. You can perform a repair upgrade of Windows 10 using the Windows 10 ISO file. As mentioned by Andre Da Costa in this forum article, performing this can repair broken operating system files while preserving your personal files, settings and installed applications. Check the article for the complete instructions.
Note: Back up your personal data and files to an external hard drive, USB thumb drive, or cloud location (such as OneDrive) before you begin the reinstallation of Windows 10 to avoid data loss.
