If the end of the circle does not end perpendicular to axis this problem disappears. Like adding a small 45 degree (90 revolved) point or "bevel" the corner in the sketch between the axis line and the circle.
I'm having trouble with STEP files sometimes too, but I've just found that importing your step file into Fusion 360 and re-exporting as STEP seems to introduce changes to the data that allow the slicer to work with it. Re-importing and exporting as STEP files this way has worked on a couple of my own original STEP exports that haven't previously imported to prusaslicer successfully, too.
Here's your PolishingBall step file after importing to- then immediately exporting from Fusion 360. This imports to prusaslicer 2.7.2 successfully for me under windows 10 giving the included 3mf file:

Note that there are errors in the mesh built by the slicer that aren't visually apparent, and that slicing succeeds despite these.
I haven't attempted to find an explanation for any of this.
There might be a clue in the fact that (in your original) the whole sphere is subtracted, leaving a concave cup:
Description of the bug
When importing STEP-File into Prusa Slicer it missas part of a revolve that is a sphere. Happens in all models I have done where part of a circle meets rotation axis perpendicularly. To exclude export errors from SolidWorks I also imported the STEP-file into 3ds Max 2024.
