Logitech G915 TLK F-keys not working

Hi! Since a couple of weeks the F-keys from my G915 TLK stopped working.
This setup has worked for years (same KVM, same keyboard, same laptop)

What I have tried so far:
- my laptop has a Windows dual-boot -> it works on Windows
- another laptop (mac) plugged into my USB-C cable -> it works
- only the F1 to F12 keys are not working, all the rest is working fine, including media keys
- my keyboard is connected with the Lightspeed Receiver. I tried via Bluetooth, same issue.

There is a FN-key, but it doesn't change if I press it.

I've tried capturing events with xev. No event is being received when I press a F-key.

I am suspecting a package update broke it, but I did not really pay attention to what has been updated when it broke (and do not remember when it started).

This is the output of dmesg when I connect my keyboard (plugging Lightspeed dongle):

Any hint on where to start / look?
