Bug Description

So I'm using Ubuntu Linux (Ubuntu 22.04.3 LTS) and I have external keyboard Keychron K3A1. It's all been working fine for a few years until some time ago, maybe a few months back, when after one of the overnight ubuntu updates made the F5 and F6 keys to stop working.

Here's the output of showkey:

--------------------------------------------------------------------------
petar@xps~$ sudo showkey
kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
keycode 28 release
// HERE I PRESS F5 and F6 multiple times but nothing is registered
keycode 29 press
^Ccaught signal 2, cleaning up...
petar@xps~$
-------------------------------------------------------------------------

and same thing is with xev. Oddly enough - it is not a keyboard broken key because Fn + F5 and Fn + F6 is working fine (dimming the keyboard light and brightening the keyboard light).

And one more strange thing happened too. I have a key on my Keychron keyboard that is supposed to take a screenshot. It was working fine, but at the same time when the other problem started happening, this key stopped working and in stead of getting a screenshot it now opens a new terminal. I think somehow now it is mapped to Ctrl + Shift:

-----------------------------------------------------------------------------------------
petar@xps~$ sudo showkey
kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
keycode 28 release
keycode 42 press // <----!!!!! This is where I press the screenshot key.
keycode 125 press
keycode 5 press
keycode 42 release
keycode 125 release
keycode 5 release
keycode 272 press
keycode 272 release
keycode 29 press
^Ccaught signal 2, cleaning up...
petar@xps~$
