Hi! Once again i'm unable to load my system's font which is working well
with MKIV.

i have followed the steps :
export
OSFONTDIR=~/.local/share/fonts:/usr/share/fonts:/usr/share/texmf/fonts/opentype/
mtxrun --generate
mtx run --make
mtxrun --script fonts --reload

without success.
This problem occurred  to me since december 2020, i update LMTX weekly from
the archlinux user repo (aur) binary.
Any suggestions?
