Just opened a spreadsheet in Numbers that I use on a weekly basis to be greeted with the warnings dialog box with a message about .AppleSystemUIFont is missing.
This is the first time I've seen this message and never had any issues with this file before.
a quick Google shows brings up very little, so any suggestions would be helpful.
