runs fine, but it crashes Glyphs if there are plugins installed. (Send a report with note “libdispatch”). Each of my plugins, if installed individually, works with the two lines above.
Again, I reduced it to this set of plugins:
(While reducing I send reports with the note “Reduce”.)
With this set, the two imports above in the Macro window crash Glyphs. Remove any one and run the two imports from the Macro window and it does not crash.
My versions are still the same: Glyphs 3.0.3 (3062), Python 3.9.1 (Glyphs), macOS 11.2 (20D64)
