@hristesp: what happens when you force GPIO9 to ground while powering on the ESP? Can you program it then?

Interesting. I used a bare ESP32-C3 chip in my design (no space for the module on the board) and ordered the PCB and assembly from JLCPCB. It worked out of the box. Even the 32kHz crystal works (initially I thought it was a hardware issue but it turned out I was dumb and it was a configuration issue).

@cyber_v1 very interesting. May I ask how you interfaced with the chip? Was it over USB or UART/JTAG? Do you have a date code?
I removed the front cap of our modules and found the units that do not function were manufactured in 2023, while the working units were made in 2021. On the front of the module the working units have XXN4 while the recent non-functioning ones have M4N4.

The interface is built-in USB.
One of the chips reads

I am having the same issues with ESP32C3 M4N4 modules. See https://esp32.com/viewtopic.php?f=12&t=39450&p=130974 does anyone have a solution?
