FWIW, I submitted a ticket to Sketch a few weeks back for this very issue and they did not blame Craft. I did however have to do a full delete and re-install from a targeted download they gave me. Since reinstalling about a week ago, I have not had the issue, and I use Craft. I did however have to redo all my custom keystrokes and saved color palettes. See support tkt here.
