Description

I have a simple keybind to replace the ± button with the ~ button. However it seems that in many cases where I need to enable the Caps-lock key the application crashes and causes my Apple Magic Keyboard 2 to disconnect. Forcing me to turn it off and on again, only to find my keybinds are no longer working.

I end up having to restart my entire laptop for the problem to go away.

I've encountered this issue many, many times over the ast few months since I have installed Catalina, am not loving this and would love to see a fix quickly.

Contributor guide

Research direction
Investigate the capslock event handling in Karabiner Elements. Look at the event queue.cpp file for state management. Understand why capslock toggling causes crashes and keyboard disconnection. Check if there are known issues with Apple Magic Keyboard 2.
