UPLOAD SKETCH ERROR WITH UNO+WiFi R3 ATmega328P+ESP8266 CH340

Hello, I've been working on a project with an ESP8266 module and the Arduino IDE, but I've hit a roadblock. Whenever I try to upload a sketch, I'm faced with a series of errors that I can't seem to resolve. The errors are as follows:
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed

Sure, if you're looking to post a question on a forum to seek assistance with the errors you're encountering, here's a draft you might consider using:

Hello everyone,

I've been working on a project with an ESP8266 module and the Arduino IDE, but I've hit a roadblock. Whenever I try to upload a sketch, I'm faced with a series of errors that I can't seem to resolve. The errors are as follows:

go
Copy code
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed

These appear after the IDE fails to upload the sketch. Here's what I've already tried:

Ensuring that the ESP8266 is correctly connected to the USB port.
Checking that the correct port is selected in the Arduino IDE (Tools > Port).
Updating the drivers for the USB-to-Serial chip that my module uses.
Trying different USB cables and ports on my computer.
Ensuring that no other software is using the COM port.
Following the typical bootloading sequence for the ESP8266 (holding down BOOT/FLASH when powering up or resetting).

I'm using Arduino IDE last version, and 1.8 and my operating system is Windows 11.

I would greatly appreciate any insights or suggestions the community might have.
