There are a lot of complex hollow structures that are giving the planar contour → closed surface conversion trouble. Likely because of this some surfaces are poorly constructed, causing a problem when converting it to a binary labelmap.
As a workaround, you can instead convert the structures to binary labelmaps by going through the ribbon model representation.

Click on the arrow beside “Create” for Binary labelmap and click “Advanced create…”:

Choose the “Planar contour → Ribbon model → Binary labelmap” path and click create:
