Glyphs failing to export Variable Font

Glyphs
1

Hello, when I try to export a variable font with Glyphs 3.4 (3410) I get an error message:

“Core !An unknown error has occurred”

I can export static CFF and TTF files okay. I am using an Intel chip mac with Sequoia 15.2

My colleague is able to export the VF from the same file using the same version of Glyphs on an M1 mac with Sonoma 15.4

I can export it okay using Glyphs 3.2 (3234), but not 3.3 (3335).

This has happened with other fonts too.

Can you help?

Thanks, Alistair

Could you send me the .glyphs file?

It works fine for me. There seems to be something going on with your machine. Not sure how to debug this.
