If your board does not have a red light turn on when you plug it in, please check your USB cable and USB power source is not damaged. If this is not the case, please check that nothing is short circuiting between pins of the ESP32. Please check the wiring around the '''3v3''' pin and '''GND''' especially, as if these are accidentally connected together it can cause the board to not turn on.
