All input blocked for enabled keyboards

[johnrwoolley]

Starting yesterday, when Karabiner Elements is enabled for any keyboard, all input is blocked for that keyboard. I can't type anything into any text boxes - as far as I can tell the only button that works is the mute button. The Karabiner-Elements event viewer still reports keypresses as normal.

Any ideas would be appreciated. My caps lock -> escape/ctrl remap is key to my workflow!

Hardware information:

macOS version: macOS 14.6.1
Karabiner version: Karabiner-Elements 15.0.0
Your Mac hardware: Apple M1 Pro 
Your keyboard hardware:
- Apple Internal Keyboard/Trackpad (Apple Inc.)
- Magic Keyboard (Apple Inc.)

Here is my karabiner.json config file:

Here are the logs, starting from enabling my magic keyboard and then typing on it a bit:

Restarting Karabiner fixed it for me, although temporarily. It came back when I woke up after standby. But it's not consistent, happens ~once in 2-3 days.

Thanks for the response. Unfortunately it is 100% consistent for me, including multiple restarts of karabiner and of my mac.
