PrusaSlicer 2.6.1 hangs while "Making Supports"

[konkers]

Description of the bug

When trying to slice the below file with the 0.20mm SPEEED profile for an Original Prusa MK4 Input Shaper 0.4 nozzle printer profile, the process hangs at 45% while making supports. If I increase the vertical shells to 3, the model correctly slices.
