Method 3: If the issue persists Perform a clean boot.
Clean Boot:
• You must log on to the computer as an administrator to be able to perform a clean boot.
• Your computer may temporarily lose some functionality when you perform a clean boot. When you start the computer normally, the functionality returns. However, you may receive the original error message, or experience the original behavior if the problem still
exists.
• If the computer is connected to a network, network policy settings may prevent you from following these steps. We strongly recommend that you do not use the System Configuration utility to change the advanced boot options on the computer unless a Microsoft
support engineer directs you to do this. Doing this may make the computer unusable.
Disclaimer : To start the computer in normal mode refer the section, "How to reset the computer to start normally after clean boot troubleshooting" from the link below
I suggest you to try the steps provided, in the link below in order to perform a clean boot on your computer.
