OS X 10.15.7
When I run flextable, it generates a segfault. I traced the problem to systemfonts::system_fonts()

I updated my OS and R, deleted and reinstalled the systemfonts package -- problem persists.
I also opened Apple's font application and "validated" all font files (I have never installed any special fonts nor is there anything non-standard (e.g., Homebrew) on my system.
Of note, I can run other functions in systemfonts without problems -- only system_fonts triggers the segfault.
Another similar setup on OS X does not trigger the same problem, so the problem is more likely something in my system rather than a problem in R.
Does anyone have any ideas on how one might address this?
