Okay, I managed to get it working on the LTS kernel (5.15.47-1). Specifically I:

1. sudo pacman -S linux-lts
2. sudo grub-mkconfig -o /boot/grub/grub.cfg
3. reboot
4. sudo pacman -S linux-lts-headers

[chinese-wzq]

I think this is a kernel source bug.Can you report it?

[bquast]

It seems to be, I'm on Arch, on more recent version of 5.18 it works again, no problem.

How should I report it?
