Glyphs stuck on export

Hi,

I have a font for which Glyphs3 is sometimes getting stuck on export with no errors (the export font dialog just stays forever). It is not always reliably reproducible; sometimes the export is fine and restarting Glyphs usually works.

I followed:

and disabled subroutines, but none of the other suggestions apply since there is no error message.

I am using Version 3.4.1 (3436) but I was using a newer version of Glyphs with this file but went back to 3.4.1 in the hope it would fix it (which it did not).

Any clues for what I can do to fix/get around this? Am happy to send the file in a private message if desired.

Thanks in advance!

Does this mean that the export usually works if you open the file but doesn’t if you worked on it for a bit?
Can you try to start without plugins. Hold down the Option + Shift key when you start Glyphs.

Yes, exactly.

Can you try to start without plugins. Hold down the Option + Shift key when you start Glyphs.

I can reproduce the error with all plugins disabled.

I case it helps, when I run “top” I usually see Glyphs using a lot of CPU when the export is working. When the export fails Glyphs disappears from top (or is so low I cannot notice where it is). I am not sure if there is any kind of logging for me to tell you more.
