HeatPump::connect(USBCDC*) error on Arduino Nano ESP32

[surfingreg]

I have everything working in the mitsubishi_heatpump_mqtt_esp8266_esp32.ino except the line hp.connect(&Serial); in setup(). If I comment that out it loads to my Arduino Nano ESP32 fine, and connects to MQTT. If I leave that line in I get this. I'm connecting to my device via USBC, to flash it. I have no intent to use the USBC connection once it's flashed and hooked up to the mini-split. Am I missing something?
