Ok, it sounds like an issue with the rpi_ws281x dependency. Make sure you're running the latest version with pip3 install --upgrade rpi_ws281x. If that doesn't work, I'd recommend filing an issue with https://github.com/rpi-ws281x/rpi-ws281x-python/

I originally tried sudo pip3 install rpi_ws281x adafruit-circuitpython-neopixel but it did not work until I tried the command @makermelissa mentioned above -- for others reading this when they get their rev 1.5 pi 4 board -- this was the fix.
