This is usually caused by a floating point precision issues when the Camera's size isn't set to a perfect multiple of your pixel size.

It's a tough issue, and there's lots of advice on it, but I think Unity may have a PixelPerfectCamera component to help with it: https://forum.unity.com/threads/pixel-perfect-preview-package.533433/

Not sure. Wish I could help more but I've only got time to try to get you pointed in the right direction.

ProCamera2D also has features to help with it, if you want to shell out money for an asset.
