AI chasing player in 2D game

For some reason my blueprint for AI chasing Player does not work. Here is what i made:

where “sphere” and whole viewport looks like this:

I tried to make it as a character, as a pawn and with “ai move to” function and “add movement input”. Nothing working whereas it was working in 3d game.
AI “see” when Player overlap with sphere but doesnt do anything.

Try removing the sphere and testing on begin play
