I'm trying to compile a very simple file where i just typed a word (in hebrew, english works fine) into a new document and tried to do "Export [PDF(XeTeX)]", but it just doesn't work. I get the error in the title. I've looked at the other threads with this same question but they seem to all use TeX, but I use LyX.
I've installed LyX and Culmus and all the things that should be needed but it just doesn't work. Help is very appretiated! thanks.
EDIT: Solved due to a full reinstall of everything related to tex.
polyglossia, you have to define a\hebrewfontcommand, sopolyglossiaknows which font to use. Tex code e.g.,\newfontface\hebrewfont{David}. (I don't haveDavid CLM). I don't know Lyx. – Cicada May 10 '21 at 11:43
