Only happens with one specific file. Crashes when exporting one or multiple istances, static and variable. Doesn’t happen in the regular release (3151).
Can you send me that file?
You have a “Disable Masters” parameter in the font settings. The Light instances depend on those masters and can’t be exported without any masters. What are you trying to do?
Oh sorry, I didn’t see it was still turned on from when I was trying to export a subset variable font.
