ESP32 S3 Nano connection

[Jimboy]

Windows 10
VS Code: 1.103.0
ESP-IDF: V5.5
ESP-IDF Extension for VS Code: Version: 1.10.2
Board: ESP32-S3-Nano - https://www.waveshare.com/wiki/ESP32-S3-Nano

I'm trying to upload the Hello World sample to my ESP32-S3-Nano.
It Builds ok. But I get the following message when I try to Flash using UART and com3 selected:
esptool.py v4.10.dev2
Serial port COM3
A fatal error occurred: Could not open COM3, the port is busy or doesn't exist.
(Cannot configure port, something went wrong. Original message: PermissionError(13, 'A device attached to the system is not functioning.', None, 31))


Note that:
I can upload to my LILYGO T7 S3 ESP32-S3 using the UART method in ESP-IDF.

I can upload a simple blink to my ESP32-S3-Nano using Arduino ide and DFU.

Only VS Code with ESP-IDF wont connect to my ESP32-S3-Nano.
