ESP8266 uploads successfully but doesn’t run after Windows 11 update

Development Tools IDE 1.x
1

Hello everyone, how are you? I'm having issues updating my sketch on the ESP8266. The upload completes without any errors, but the ESP8266 is not updated. This problem started today, and I've already tried reinstalling the Arduino IDE several times and testing both versions 2.3.4 and 1.8.19. I also tried simple codes, like the one below, but it didn’t work either:

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

void loop() {
  Serial.println("hello");
  delay(1000);
}

I think this started after a Windows 11 update since I didn't make any hardware changes. I just updated the previous sketch, and the problem began. The USB port is correct, and I am using the NodeMCU 1.0 board. Below is the output:

While I have no reason to believe there is a problem with the connection my first step in finding the issue would be to check the connection.
You may find the information on my page here useful

what do you see on the serial monitor?

The program has uploaded, any chance you have changed the board settings or are you using a different core version now ?

That is a normal upload. Did you press the reset button after it says 'Hard resetting ....
