Karabiner-elements: Manual re-install required after OS update

[gelraen]

Updated to Mac OS X 10.14.6 today and Karabiner stopped working. Pressing restart button in the Misc tab didn't help at all, as well as ignoring and unignoring the keyboard in the Devices tab. Also, there's no indication of any issues, other then things simply not working, e.g., my caps lock doing caps lock stuff, instead of being remapped to F19.

I also remember the same thing happening after the previous OS update. At this point even a simple popup asking for re-install would be a huge step forward in avoiding spending a lot of time debugging the issue.

Log after re-install: Karabiner reinstall log 2019-07-31.log

I had the same issue after installing 10.14.6

Also suddenly a rule I installed to change capslock to shift+cmd+control was now changed to shift+cmd+alt+control.

Had to rebind some keys in BetterTouchTool because of this. Not huge, but didn't expect at all

TL;DR

1. Quit Karabiner
2. pgrep karabiner | xargs sudo kill -9
3. Start Karabiner

=======================================================

Installed the Supplementary Update today and had the same problem - Karabiner was effectively not working.

I restarted Karabiner, but no effect.

Quit Karabiner and came here looking to see if this had been reported.

I then killed all remaining Karabiner processes running as root. Launchctl did restart them all.

After starting to reply here, I wanted to show output of ps axuw | ag -i Karabiner. Noticed Karabiner was not running and started it.

Surprisingly - (Karabiner was down for 17 mins) - all is well now. There were no errors in the Karabiner log.

I had similar errors to @gelraen - when Karabiner was not working:

grep 'd errors from @gelraen provided log:

HTH.

CapsLock behaviour in my Hyper key setup broke on MacMini some days ago -- probably related to upgrade to 10.14.6. Fresh installs of 12.5.0 and 12.5.7 don't help.
But 12.5.7 on 10.14.6 on MacBook Air work fine. So it made me think it's the keyboard on my MacMini, but swapping in another keyboard has the same issue.
Looking in EventViewer on MacMini with no modifications running, it seems that I get the expected caps_lock key_down event, but not the expect key_up event. Whereas on MacBook I get both key_down and key_up events.
No errors in log.
Weird.

Tab key and Caps lock key stopped working after Mac OS X 10.14.6 update. This seems to affect only my External Apple Keyboard(wired). The one on the laptop seems to work fine. Checking in event viewer pressing capslock and tab key(tilde and escape key too) don't capture anything. Tried following:

1. Restart the system
2. Reinstall Karabiner
3. Check karabiner config to ensure it matches my previous config
4. Quit Karabiner and pgrep karabiner | xargs sudo kill -9
5. Restart the sytem
   None of these steps seem to work for me. Sharing my Karabiner config. Is there any other step which I should try to make it work?

My Cmd + Tab combination doesn't seem to work, I have tried uninstalling Karabiner to atleast make the system usable, but removing Karabiner and restarting the system doesn't seem to help. Any suggestions on this will help.
