Glyphs keeps freezing

Hi there, my app has starting freezing every time I try to export interpolations. It’s pretty sporadic, sometimes it works but mostly I just get the pinwheel of death. Has this been happening to anyone else? I’m not sure if it’s my file ( was working fine until last week) or an app update.

Yes, it’s still hanging for me sometimes when exporting. I don’t have interpolations, just two master weights.
