I'm getting an error while uploading my code to esp8266 via an arduino (FatalError('Failed to connect to %s: %s' % (self.CHIP_NAME, last_error)))

Arduino: 1.8.13 (Windows 10), Board: "Generic ESP8266 Module, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), dtr (aka nodemcu), 26 MHz, 40MHz, DOUT (compatible), 1MB (FS:64KB OTA:~470KB), 2, nonos-sdk 2.2.1+100 (190703), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

Sketch uses 257316 bytes (26%) of program storage space. Maximum is 958448 bytes.

Global variables use 26816 bytes (32%) of dynamic memory, leaving 55104 bytes for local variables. Maximum is 81920 bytes.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

I’m getting the above stated error message while I’m trying to upload a code to esp8266 via an arduino(I’ve removed the ATMEGA32 from my arduino). Sometimes it gets uploaded without a problem(very rarely) but mostly the upload fails.
I connected rx of arduino to rx of esp and same for tx too. 3.3v of arduino to enable and vcc of esp. graund of arduino to ground of esp and gpio0.

The code that I’m trying to upload:

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);     // Initialize the LED_BUILTIN pin as an output
}

// the loop function runs over and over again forevervoid lop() {
  digitalWrite(LED_BUILTIN, LOW);   // Turn the LED on (Note that LOW is the voltage level
  // but actually the LED is on; this is because
  // it is active low on the ESP-01)
  delay(1000);                      // Wait for a second
  digitalWrite(LED_BUILTIN, HIGH);  // Turn the LED off by making the voltage HIGH
  delay(2000);                      // Wait for two seconds (to demonstrate the active low LED)
}

My settings:

EDIT: Also, I want to add one more thing when the message box says "Connecting…….._____….._" during that time if i reset the esp the code starts uploading
