I believe running rpi-backlight as root requires a slightly different installation process - and isn't recommended nor necessary after creating the udev rule.
Please try running without sudo.
Btw, -n is not a valid option in either v1 or v2 - see https://rpi-backlight.readthedocs.io/en/latest/usage.html#command-line-interface

Linus,
You are correct, on both fronts. (sudo, -n)
Last night, I used sudo as a fallback when initially receiving errors (not shown above). Since then, I've rebooted the system several times and the CLI and GUI now work flawleslly.
Thank you ... Allen.
