ESP32 c3 wroom02 flashes but monitor shows invalid header: 0xffffff0f error

I want to run the esp32c3 wroom 02 card with at commands with the docklight application, but I get the error "invalid header 0xffffff". can you help?

Likely something went wrong with flashing the firmware. Can you tell how you flashed it? Are you sure you selected the correct firmware for the chip? (E.g. esp32 vs esp32-c3)

<t>Hi everyone,<br/>
<br/>
I've been researching the ESP32-C3 flashing circuit and have designed a basic circuit for flashing the ESP32-C3 SMD board. However, when I try to flash the basic blink example code, I encounter the following error: "COM5 failed to connect: Failed to connect to Espressif device: No serial data received."<br/>
<br/>
I've also attached the PCB design for reference.<br/>
<br/>
Any advice on how to resolve this issue would be greatly appreciated.</t>
