Do you mean “wipe cache” as  delete “luatex-cache/context/5fe67…f32e/fonts” folder? 

I open the terminal and run “mtxrun —script — reload -force”, then I got

mtxrun          | ConTeXt TDS Runner Tool 1.32
mtxrun          |
mtxrun          | no script name given, known scripts:

Do you mean “mtxrun —script —reload —force fonts”?
