File Signature Verification is a feature that allows checking the unsigned drivers installed from the third-party software. Follow the steps to check if there is any unsigned driver that causes the error: –

8.2 Uninstall Drivers With DDU

DDU or Display Driver Uninstaller is an application for Windows that offers to remove drivers completely from the computer. Usually, we use a device manager instead of any software. However, the device manager does not remove the drivers entirely and due to this some files may be left behind, which can cause a conflict among drivers. We recommend DDU over the device manager.
