Error message says it is attempting to invoke virtual method but i am not sure whether it is about particular application or OS level.

Answer 1

Do you have the app light manager installed? It should be that app generating this pop up. It's not a problem but it's annoying. It should be fixed, I have it too: Pixel XL, Nougat 7.1.1
