You could either use a real font name like 'Arial' or a symbolic name
defined with \definefontsynonym like 'Serif', 'SerifBold', 'Sans',
'Dummy-Regular' etc. in the second argument of \definefont but not
the name for a font collection defined with \definetype, in your case
\definefont[myChapterFont][Sans sa 1.728]
or
\definefont[myChapterFont][DummyRegular sa 1.728]

This did happen because Latin Modern Sans is the default sans serif
font,
you have to define a typescript with the desired font as sans style or
you
use a symbolic name for 'myChapterFont', in your case 'Dummy-Regular'.
\starttypescript [myBodyFont]
\definetypeface [myBodyFont] [rm] [serif] [myBodyFont] [default]
\definetypeface [myBodyFont] [ss] [sans] [myHeadingsFont] [default]
\stoptypescript
works with the definition from you because it use now Arial as sans
font.

The correct definition is:
\setuphead[chapter][style={\tfc\ss}]
