Could be anything. At the bare minimum, we'd need to know your OS and the hardware you're using this on. Please also post what you already tried yourself.
You are trying to program the device via the serial port, but the connection to your board seems to be via JTAG. Either hook up the serial port, or use OpenOCD to upload via JTAG. (Also, with GPIO0 fixed to 0, your ESP32 will never boot from flash; you may want to look into that.)
