I have installed Latin Modern Roman fonts (on Windows), and in the past I was always able to use them with
FontFamily when making plots, etc. Recently, however, I have encountered a problem where Mathematica does not recognize that these fonts are installed, and they don't appear in
$FontFamilies. If I reinstall the fonts (in which case Windows tells me the font is already installed) while Mathematica is running, then it will recognize them until I close it and reopen it, after which it "forgets" again. Is this a known issue and is there any way to deal with it?
Version: Mathematica 13.1
