Question 2d lights have weird edges when pixelated

im trying to add lights and shadows to my game however, all the shadows have really weird blurry edges that dont look good,


pixelated

nonpixelated
in the nonpixelated, the shadows have really sharp clean edges so im not sure why the pixelation is making this blue, is there any way to fix this or should i go about lights in a different way
i was trying to get the lights to render on a different camera so they wouldnt be pixelated, but i dont think that worked,
id be open to not pixelating the lights if possible but im not sure how to go about that
