There is a known regression in SOLIDWORKS 2017 SP3 with regards to saving eDrawing files. If you attempt to save an assembly as an eDrawings file, either through the File > Save As or Publish to eDrawings command, it will cause SOLIDWORKS to crash. This issue is being addressed by SPR 1024994 by the SOLIDWORKS development team.
At the moment, the workaround for this issue is to open eDrawings, load the native SOLIDWORKS file, then perform the save option within eDrawings to save the part.
