Does Fusion actually crash here (that is, do you see a Crash Report dialog)? Or, more likely, is Fusion just VERY busy, and you think it has crashed? Just looking at the PDF here, I can see that there are probably tens of thousands of very tiny lines in this SVG, and this will cause Fusion to struggle. You mention that "Blender imports svg files easily", but that is a very different operation in Blender. Fusion has a constrained sketch environment, which requires a lot more processing than I suspect Blender needs, so the comparison is not really valid. Most likely, @jhackney1972 succeeded because he was very patient, and just waited for the operation to finish.
