Missing Geometry from simple shape
PrusaSlicer seems to have trouble slicing the upper half of this model. It's a simple shelled one layer shell designed in Fusion360. It seems to work fine in Cura.

I've also found that Cura is more forgiving on some wonky .stl files than is PrusaSlicer.
Although PS is my main slicer for the MK3S, I do use Cura for cases like this.
For many (definitely not all) .stl files that will not slice properly with PS, I've found that importing the .stl into FreeCAD, then convert to shape -> refine shape -> convert to solid and a re-export will often result in a .stl that will slice and print as expected with PrusaSlicer.
RE: Missing Geometry from simple shape
Loading the model I see no problem slicing (2.2.0 + Alpha 2.3.0).
Please zip the PS project file and upload, this way it will be easier to troubleshoot.
Have a look at my models on Printables.com 😉
