Typically if any crash occurs it would involve the option Output Polygons set to "With Cutlines (for Islands)". Using Cut-Lines in polygons can result in very massive polygons, that sometimes cause problems for some CAM software tools (used by other vendors and manufacturers). For best results use "Without Cut Lines (for Islands).
Another preferred solution instead of "Boolean Wizard" is to use "Build Composites". Here's a link with more information about using Build Composites instead of Boolean Wizard, https://support.numericalinnovations.com/support/discussions/topics/14000014877
