CGAL error

union(){
difference(){
import("D:/Core XY/D-Bot_latest/files/1-Hotend_Clamp_E3Dv6.stl",convexity=10);
translate([0,0,-0.5]) cube([50,20,43]);
translate([0,20,4]) cube([50,30,43]);
}
translate([13,23.5,0]) cube([15,12,4]); //fillin
}
Using F5 this displays properly but F6 render just ends up with the fillin and no Hotend clamp/

This is the error
ERROR: CGAL error in CGAL_Nef_polyhedron3(): CGAL ERROR: assertion violation! Expr: e_below != SHalfedge_handle() File: /mxe/usr/x86_64-w64-mingw32.static.posix/include/CGAL/Nef_3/SNC_FM_decorator.h Line: 426
