I have a Microsoft sculpt keyboard connect via usb to my Catalina MBP 16,1. Suddenly, the ^ key has traded roles with the < key. The internal keyboard has the same problem. Everything else is the same, but those two have suddenly switched.
This came after an unsuccessful attempt to install Karabiner Elements which seemed super unstable. It did not occur right after that, as I used the keyboard for some time then.
How can I find out what the problem is, and fix it?
Update: After two rounds of reinstalling Karabiner, Uninstalling Karabiner, and Rebooting, the problem now only affects the external keyboard.
