ESP32-C6 with Two A02YYUW Sensors: Crashes When Second Sensor Is Enabled

I don’t know your board and how usb serial is implemented, but you could try disabling it:

logger:
  baud_rate: 0

also, try with default uart0 pins:

uart:
  - id: uart_1
    tx_pin: GPIO16
    rx_pin: GPIO17
    baud_rate: 9600
