I am not able to update. Can someone help?

I am getting this error whenever I try to update. Wondering how to fix it.04

Does this help:

The update link didn’t work. But the step-by-step guide did work. Thank you @GeorgSeifert
When I restarted Glyphs, it asked me to share the crash report, which I mailed to support@glyphsapp.com
Thank again.
