I need help, CURVE CLOSEST POINT IS NOT WORKING

Both initial geometries have the curves and the points, I need those points projected on those curves so that I can use the shatter component. Can someone help me please?
Thank you very much,
Guadalupe!

Here is a way


The big problem is that the trees don’t match. So I flatten the points, graft the curves. And then just choose the intersection that are near the curves.
