Newbie lost trying to get LEDs to work

I built an hyperion ambilight setup but cannot get the lights to work. I'm sure that to someone with more experience, this will be easy to resolve. I've attached the debug log. TIA!

I have a Raspberry Pi4. I followed the Ambilight Tutorial from Chris Majestic. I have BTF-LIGHTING WS2812B LED strip hooked up to the GPIO on the Pi. Here is the link to the tutorial I followed:

It's already running with root.

Do you have a live image in Hyperion?

Yes, I have a live image in Hyperion.

You need to update to a newer version of the Ws281x Library. Try Hyperion‘s nightly build.

I found the nightly build, installed it, and it works! Thank you so much for the help!
