Glyphs fil will not open after adding 'add missing symbol glyphs' custom parameter

Hi there,
I recently started using Glyphs. I attempted to add the custom parameter ‘Add missing symbol glyphs’ to my font and the application crashed on export. Glyphs will not open the font file now.

I saw a previous post describing the same problem. The response was;
‘What version of glyphs do you have?
Can you send us the .glyphs file (support at this domain)?’

I am using Version 2.2.2 (826), should I send my file?


Yes, please send the file (to support at this domain).
