The forum post for this is Adafruit Forums: Errno19 after few minutes running. The program running on an ESP32-S2 has an extra scd.data_available call immediately beforehand with no intervening statements:

    #Read SCD30
    if scd.data_available :
        label_scd2.text = str(int(scd.CO2))
        print("CO2:", scd.CO2, "ppm")

There's a slightly different SCD-30 with Pi 4 issue reported on Adafruit Forums: SCD-30 I2C detection error on Raspberry Pi 4B.
