Re: Saving preferences doesn't work

Use another variable to check valid NVS content.
read this, if variable != 0x5A (or any fix value) then write this variable to 0x5A in NVS, and set all variable to default.
The NVS content don't guarantee the default empty value 0x0!

Re: ESP32 unable to execute uploaded program

This not a blink.
try, and check serial console:
void loop() {
Serial.print(".");
digitalWrite(ONBOARD_LED,HIGH);
delay (1000);
digitalWrite(ONBOARD_LED,LOW);
delay (1000);


}

Re: ESP32 SD card info

The pinout change in your source:
SPI.begin( 14, 2, 15, 13); // The bultin SD card SPI for WROVER
void begin (int8_t sck=-1, int8_t miso=-1, int8_t mosi=-1, int8_t ss=-1);// this SPI.begin defined in spi.h
