Fix 2 – Perform a Clean Boot
Booting your system in clean boot mode helps to identify errors caused by third-party applications installed on your PC. If you don’t see the error after a clean boot, then there is some conflicting third party application that is the reason for this error.

If the error message is not seen, then you need to look for the program that is raising this error. You need to look at all the recently installed apps and try uninstalling them from your PC. On a trial and error basis, you can try removing the 3rd-party apps one at a time.
Fix 3 – Reset the IP Configuration

Check if you are still seeing the error.
