Those calls refer to libraries from the OCC geometric kernel. I'm not sure there's anything that can be done here. It's possible that the original STEP file is faulty. It may be surprising, but some commercial CAD packages have very poor STEP export capability.
You could try importing the STEP file in another CAD program or viewer. For example there is CAD Assistant, a viewer made by Open Cascade (maker of the OCC kernel that FreeCAD uses). There's a Windows version. https://www.opencascade.com/content/cad-assistant
