If you compile with lualatex or pdflatex you see in the log at the
end the fonts used with absolute pathes, e.g.

c:/texlive/2022/texmf-dist/fonts/opentype/google/roboto/Roboto-Regular.otf
or
c:/texlive/2022/texmf-dist/fonts/type1/public/amsfonts/cm/cmss10.pfb

This info isn't provided by xelatex (as the actual font is included
by xdvipdfmx). With \XeTeXtracingfonts=1 you get a quite sensible
replacement. Debugging font problems with xelatex typically start
with the advice "add \XeTeXtracingfonts=1 and then show the
log-file".
