Metal error iOS Building

Hi everyone!!! I am trying to test on ipad with windows and unreal remotely connected with macbook. Unfortunately although I have installed metal developer tools 3.0, at build time, I always get this error:

UATHelper: Packaging (IOS): C:/Users/Fabiana Carboni/AppData/Local/Temp/MetalShaderCompilation/29832/18546_1939899247.metal(0): Failed to compile C:/Users/Fabiana Carboni/AppData/Local/Temp/MetalShaderCompilation/29832/18546_1939899247. metal in bytecode C:/Users/Fabiana Carboni/AppData/Local/Temp/MetalShaderCompilation/29832/18546_1939899247.air, code: 1, output: metal.exe: error: no file or directory of this type: ‘Carboni/AppData/Local/Temp/MetalShaderCompilation/29832’.
