It looks like the remaining issues are due to the angles of the cracks being too extreme. Notice how the top of this part has a lip that would block the ray from hitting the surface behind it:
I’d recommend turning auto smooth off for the high poly as well, and smoothing out that section so that there isn’t any portion that cannot be reached by a ray coming from the low poly normal. You can still use a crease but it can’t cause an overhang.
