Thanks for all the responses. I was able to figure out the issue. @ESP_Sprite based on your recommendation, I used a logic analyzer, and found out that the ESP32-C3 module was "Waiting for USB Download", while I was programming through serial. Thanks @pataga for your recommendation to look into GPIO...

leads me to think you may have mis-interpreted something in how to hook up that module, as in, it may not be your soldering process at fault. Can you share your PCB / schematic here? I have attached the schematic of the programmer and the esp32-c3-module on the custom PCB - If you power on the modu...
