Did something change with regard to \definefontfamily recently.
I have an old document where I use:
\starttypescript[mainface] \definefontfamily[mainface][rm][Libertinus Serif][features=default] \definefontfamily[mainface][ss] [heros] [features=default] \definefontfamily[mainface][tt] [dejavu] [features=none, rscale=0.85] \definefontfamily[mainface][mm] [LibertinusMath] \stoptypescript
\setupbodyfont[mainface,12pt]
On the recent LMTX (2020.09.05) I get
selectfont > the requested font 'Libertinus Serif' has no files for the 'tf' alternative, Latin Modern is used instead. selectfont > the requested font 'heros' has no files for the 'tf' alternative, Latin Modern is used instead. selectfont > the requested font 'dejavu' has no files for the 'tf' alternative, Latin Modern is used instead. selectfont > the requested font 'LibertinusMath' has no files for the 'tf' alternative, Latin Modern is used instead.
I can find the fonts using mtxrun --script fonts. For example:
$mtxrun --script fonts --list --pattern="LibertinusSerif" --all identifier familyname fontname filename subfont instances
libertinusserif libertinusserif libertinusserif libertinusserif-regular.otf libertinusserifdisplaynormal libertinusserifdisplay libertinusserifdisplay libertinusserifdisplay-regular.otf libertinusserifdisplayregular libertinusserifdisplay libertinusserifdisplay libertinusserifdisplay-regular.otf libertinusserifinitialsnormal libertinusserifinitials libertinusserifinitials libertinusserifinitials-regular.otf libertinusserifinitialsregular libertinusserifinitials libertinusserifinitials libertinusserifinitials-regular.otf libertinusserifnormal libertinusserif libertinusserifitalic libertinusserif-italic.otf libertinusserifregular libertinusserif libertinusserif libertinusserif-regular.otf
and similar for the other fonts.
Any idea on what is going on and how to debug.
I can't reproduce your Libertinus problem but the sans serif and monospaced fonts just use the wrong names. \definefontfamily [mainface] [rm] [Libertinus Serif] \definefontfamily [mainface] [ss] [TeX Gyre Heros] [rscale=0.85] \definefontfamily [mainface] [tt] [DejaVu Sans Mono] [features=none,rscale=0.85] \definefontfamily [mainface] [mm] [Libertinus Math] \setupbodyfont[mainface] \starttext \rm\tf Regular \it Italic \bf Bold \bi BoldItalic \ss\tf Regular \it Italic \bf Bold \bi BoldItalic \tt\tf Regular \it Italic \bf Bold \bi BoldItalic \stoptext Wolfgang
