After some time of inactivity, the keyboard - Microsoft Ergonomic Keyboard - starts acting as if the Option (Win) key is pressed. Pressing the key does not reset its state. The only solution is to flip the keyboard over, and take out the battery for a couple of seconds. Started happening after upgrading to Catalina 10.15.7.
It happens pretty regularly, but only if the computer is idle for maybe 10+ mins.
Anyone seen this?
UPDATE: This only happens on the external keyboard, the built-in keyboard is fine. It's probably a bug in Karabiner Elements, which I had to upgrade after upgrading the OS.
UPDATE: It wasn't Karabiner, I uninstalled it. Sounds like a keyboard driver bug.
