With a fresh install of OrcaSlicer (built from 1.8 beta source or latest available 1.8 beta artifact from github actions)
%appdata%/Orcaslicer removed
Run Orcaslicer.
During setup, select Ender 3 v2 (I tested one other random printer and had the same result)
Keep all printer defaults and no network plugin.
When setup is finished, add object to the plate (I did cube primative)
Under strength, set "Sparse infill pattern" to "Adaptive Cubic"
Slice the plate

Exception is thrown in Slicer::FillAdaptive::FillContext

Message dialog opens: "A fatal error occurred: 'Access Violation'. Please save project and restart program" (and sometimes clicking ok will cause the program to crash completely)
