Glyphs app crashing after trying to export!

Hi there! I’ve been having trouble exporting my font into a .ttf file for a while now, it is for my school’s end of the year assignment and I’m unable to use it as a font because every time I try to export it the Glyphs app crashes immediately. I have tried restarting and resetting my computer and the app itself, but it still seems to have the same problem, is there any way of solving this issue?

Please let me know if you can asap!
Thank you so much,

Emily

What version of Glyphs do you have? Can you send me that .glyphs file?
