Gradient layer doesn't work

MaDog

Hello! 

I have a problem with gradient from procedural layers. It doesn't work. When I am creating this layer I have an ERROR (Error: CPR ERROR: 000|#include <metal_stdlib> ).

Marmoset Toolbag 4 v.4.02 (4020), macOS Big Sur 11.2.3

Message from console when I am creating procedural gradient:

CPR ERROR: Compilation failed: 

program_source:1176:12: error: call to 'clamp' is ambiguous

                result = clamp(coord.y, 0, 1)*2;
