Hi Matt

I suggest to also test what happens if you start the system
without using lightdm or X.

One way to do this is to boot into multi-user text mode.

You can do this in grub by following the instructions here:
https://docs.fedoraproject.org/en-US/fedora/rawhide/system-administrators-guide/kernel-module-driver-configuration/Working_with_the_GRUB_2_Boot_Loader/#sec-Making_Temporary_Changes_to_a_GRUB_2_Menu

Assuming that your system uses systemd, use the grub built-in
editor to add the below text at the end of the 'linux' line:
  systemd.unit=multi-user.target

And then boot. Let us know the results.

If the keyboard works at the text login prompt, then I doubt
that the kernel is the appropriate place to report this bug.
