Crash when starting up Kern On

I get an app crash when trying to start up Kern On. Glyphs 3.2 [3232] and just-updated Kern-On 1.27. Anyone else seeing this? cc: @TimAhrens

Did you re-start Glyphs after updating Kern On? (Sorry, my standard question, I wish Glyph simply enforced this.)

It would be great if you could send me the .glyphs file. Then I can have a closer look and I’m sure the bug fill be fixed quickly.

Yes, restarted the app (and it restarted with every crash too!). I’ve sent a file to the askme email address. Thanks.
