When you restart the app, do you get the Problem Report for Glyphs, like described in the Crashes tutorial? Please always send these by clicking on the button. The more the better.
The crash report you posted here indicates a memory management bug. I have been trying to reproduce it, but cannot. Are you using any system or memory optimizers on your Mac?
I tried all suggestions in the Crashes tutorial : latest cutting edge version , disable plug-ins, try with different document, delete the prefs, delete autosaves… And it still crashing
Can you try in a different user on your machine? Create a new user in System Preferences, switch to that user and try to reproduce the problem. If it is not crashing there, it has to do with something you installed or set in your user locally.
Any other helper tools installed? CleanMyMac, MacKeeper, MacCleaner? Finder enhancements? Memory optimizers, defrag tools?
I tried to reproduce the bug in a different user and it seems there was not crashing there.
In my principal user session, I uninstalled CCleaner and Windscribe but nothing changed. And now I just uninstalled BlueStack, a Microsoft Windows emulator, and I try to reproduce the crash and nothing happen. It’s seems BlueStack was the problem.
