Karabiner-Elements: Karabiner stops working after a while in Catalina 10.15.4

Karabiner works fine in macOS Catalina 10.15.4 but after a while stops working as mapping keys no longer seem to work and logs start complaining with

This is related with Issue 1932 and other people are complaining the same since a few days ago (with the exception that is not necessary to set the laptop to sleep)

Yes, I can confirm, it’s still happening.

A variant of this still seems to be present on the latest macOS (12.6) and stable Karabiner-Elements (14.10.0). A full reboot is the only thing that “fixes” it – neither the in-app quit/restart nor killing the Karabiner processes via Activity Monitor does anything.

Same here - happens when I use caps lock too many times. Currently on version 12.10.1 and Catalina 10.15.5. Attemped to unload and reload kext but was unable to do so (Failed to unload org.pqrs.driver.Karabiner.VirtualHIDDevice.v061000 - (libkern/kext) kext is in use or retained (cannot unload))

Seeing it on 12.9.90 (? seems oddly high, but:

Karabiner-Elements 12.9.0 is currently the newest version available.
(You are currently running version 12.9.90.)

…anyway) – what seems to happen for me is that using CapsLock too many times kills it. I swap CapsLock and LeftCtrl. Only fix is a restart (though in fairness, I haven’t tried a logout/login, it’s just that they’re basically equivalent so I don’t bother). This is a bog-standard USB PC keyboard. macOS 10.5.5 19F101 on a MacBookPro11,3.

Same issue here - MacBook pro 2018, macOS 10.15.7, Karabiner-Elements 13.3.0; stops working after sleep, quit and restart of application fails to work, however logging out of my macOS user account and re-logging in fixes it (without restart).

Same issue here today with 12.10.0 and macOS 10.15.5

I’m on 10.15.4 and I’ve had no issues.
