Crash when lowering extruder number to 0 in PS 2.7.0 RC1

[ElianaRose66]

Description of the bug

When I lowered the extruder number to 0 in perimeter extruder, infill extruder, or solid infill extruder for multiple XL input shaper and non input shaper print settings, PrusaSlicer immediately crashes every time. This is on an M2 Mac, even with no STL loaded in and all stock settings.
