I have the same problem.
I tried to slice this file and it stops at 70%.

It doesnt matter if I use a profile based on 0.2 or an original profile from Prusa.

I have the same issue with a mammoth head I was trying to slice. Works fine in 2.5.0, but not in version: 2.6.0-alpha5 Again, stuck at 70% and I left it for 3 hours. Tried multiple times with different settings but same result.
Tried 0.1mm, 0.2mm, 0.3mm both draft and quality, then with and without supports, and tried 15%, 20%, 25%, and 30% infill. The same result, freezes at 70% Infilling layers.

I have the same problem, but only with organic support and after I changed Extrusion width for support material to 0.18.
Gets stuck at 70% Generating supports.
Setting Extrusion width to default value or 0 works no problem.

I encountered the problem again and when I switch to edit mode and back to preview mode then it looks as if Prusa cant fill the object.

I sliced the file in Cura and it was working without a problem. I assume it has nothing to do with the file itself.

Thank you guyes, from the first look it is cause by arrachne end with:

  • PrusaSlicer-2.6.0-alpha5+172
    Slic3r::Arachne::SkeletalTrapezoidation::separatePointyQuadEndNodes()

But let's see after more deep investigation.

…rated Voronoi diagram.

Boost Voronoi diagram produced degenerated Voronoi diagram. This Voronoi diagram was detected by our method for detection of those types of degeneration. But rotation by PI / 6 wasn't able to fix it.
So now, when the Voronoi diagram is still degenerated after the first rotation, then we try another rotation by different angles to fix the degenerated Voronoi diagram.
