All of a sudden NIS 20.1.1.2 "Real Time Protection" is OFF

Hello,

 

From 20 October morning all of a sudden NIS real time protection is off by default. Even though I turn it on, its reverting to OFF state. Also I am not able to scan my system completely. Attching are the errors that I am recieving. Please guide me. I have been using NIS since 5 years, never faced this problem.
