Sure thing! Ok, so it looks like one problem is due to the mirroring – it matches the high poly on the left side but not on the right:

You could either fix it so it’s the same on both sides or just turn off the rendering for the mirror modifier. I also marked a couple more edges as sharp:

After that I joined the two parts of the high poly together and edited the geometry to make them one mesh (or you could bevel the edges – anything to get rid of that sharp line) to fix this seam:

Once you do that, it should bake fine!
