I'm closing this as a duplicate of #8435.

You are using automatic extrusion width (set by entering zero in Print Settings->Advanced->Extrusion width->Infill) and in PrusaSlicer 2.5.0-alpha2 this isn't handled correctly.
Also it was fixed with 7783915, and it will be part of the next alpha.

Now I'm getting this issue, rather than just a hang. I've compiled from source from the newest 250_master branch.

@lbibass Thanks, reproduced (I had to switch from Arachne to Classic perimeter generator to reproduce your issue). We will look at it.

As mentioned above, you must select an extrusion width in 'advanced' and not use the default width '0'.
With nozzle 0.4, 0 = 0.45
So change 0 to 0.45

@lbibass Your issue with the Infill failed error message should be fixed in master_250 with the commit 38ca763, and it will be part of the next alpha. So I'm closing this issue.
