Arduino C++ Arduino Uno, ESP8266 CH340 driver problems with Windows 11

After Upgrading my computer to Windows 11 I had some ESP8266 D1 Mini and Arduino UNO with the CH340 chips fail to upload while others continued to work.
The boards work pefectly under Windows 10 but fail under Windows 11 with messages like:
avrdude: ser_open(): can't set com-state for "\\.\COM5"
Failed uploading: uploading error: exit status 1

This video shows the issue and how to fix the problem.

For more information, drivers and a walk through of how to fix the issue go to:

Thank you it works now! I had 2 ESP8266 boards (No writing on chips) and they wouldn't connect to the Arduino IDE. The driver was 3.8.2023.2 and I installed 3.5.2019.1 like you mentioned. Changed the driver and, it finally recognized it! I figured the boards were broken but, nope just the drivers! I'm on Windows 11 Pro as well.

Thank you!. All of my clones have the driver problems. I keep a shortcut on my desktop for when it goes wonky. I couldnt find where to turn off the updates

Thank´s for this publication, I was very ilusionated to solve my comunicatios problem between Arduino mega and W11 and I have intented a lot of times to change the driver but there was no choice - the 3.8.2023.2 driver does not disappear.... Could you give me any new idea ? The Event Manager response is "0".
