502GA - Intermittent Keyboard Backlight issue

I'm seeing an issue where the keyboard backlight works intermittently. It seems to be related to sleep/hibernation. I'm running on Manjaro with the 5.9.16 kernel. When I attempt to run asusctl -k low, I get the following error:

Error: MethodError("org.freedesktop.DBus.Error.UnknownObject", Some("Unknown object '/org/asuslinux/Led'"), Msg { type: Error, sender: ":1.959", reply-serial: 7, body: Signature: [ s (115), ] })

Just as a note, this is an intermittent issue. I'm just not sure what's causing it to fail or work at different times.

Thanks
