ESP32 Devkit v1: A fatal error occurred: Failed to connect to ESP32: Invalid head of packet (0x00)

I can’t upload my code to the board.

void setup(){
  Serial.begin(9600);
}

void loop(){
  Serial.println("Kavabanga");
}

When I try to upload this code to the board I get the following message:

esptool.py v2.6
Serial port COM3
Connecting........_____....._____....._____....._____....._____....._____.....____An error occurred while loading the sketch.

A fatal error occurred: Failed to connect to ESP32: Invalid head of packet (0x00)

I tried to combine the keystrokes(boot, en), add a capacitor by 10 uF, reduce the download speed from 921600 to 115200. None of this worked. Once I also got this message:

A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

I hope knowledgeable people will help the newbie)) Thank you in advance for your help.
