[NTG-context] error with \sc

Hi, With ConTeXt version 2024.04.01, the \sc command produces an error: fonts > preloading latin modern fonts (second stage) fonts > 'fallback modern rm 12pt' is loaded pages > flushing realpage 1, userpage 1, subpage 1 close source > level 1, order 3, name './test.tex' backend > xmp > using file '/opt/context/tex/texmf-context/tex/context/base/mkiv/lpdf-pdx.xml' mtx-context | fatal error: return code: 1 Test file: \starttext \sc test \stoptext Is this a bug, or some misconfiguration of my installation? TIA for any hints, -- Peter
