How do I stop sprite movement on 3 key pressed?

I have 8 directions sprite, so when i use for example left and up arrow, he goes diagonally up, but if i click left,up and right arrow, the animation freezes and goes up. I tried using if left,up and right arrow are pressed "Stop 8 direction" but it continues to go upwards even if very slowly. I would like the sprite to stop when 3 keys are pressed.

Thanks, it works
