Hello, good afternoon. I've been trying every possible solution for almost a week now, and I keep getting the same error. I've tried installing drivers, installing libraries, changing cables, shorting IO0 to GND, and even adding a capacitor between EN and GND—all to no avail. This board is brand new, and it worked fine the first time, but it hasn't worked since. I need help, please, and thank you for reading.

    1. No capacitors should be installed between EN and GND.
    2. Perform a communication test following these steps:
      1. Connect the device to the computer.
      2. Open the serial monitor, select the port corresponding to the device, and then connect.
      3. Press RST on the device.
      4. What will be displayed on the serial monitor?
