I am just guessing, but I think that Arachne slicing algorithm doesn't work when you just have a very thin single wall. So, for example, you have a thin wall of 0.2 and a 0.4 nozzle (line width) then the option print thin wall will bring the slicer to slice this part.
The Arachne algorithm would adjust the inner wall in case your wall thickness is not a multiple of your live width, to get a smooth extrusion.

Is my question so dumb, or so tricky?
To my understanding the new slicing algorithm and the fact that it can vary line widths is THE most significant improvement in Cura 5. So the existence of the "print thin walls" option is quite confusing. Would it disable Arachne and switch back to the old engine?
