SGP41 not found after a power cycle

After power cycling my AirGradient ONE, I am no longer getting and PM, NOx, and VOC measurements. CO2, humidity, and temperature are fine. I saw a brief message on the screen as it booted up saying that the SGP41 was not found.

I’ve power cycled it several times, and I get the same results. I’m on the 3.6.0 firmware.

Any ideas, or did the sensor go bad?
