PlatformIO says COM port doesn't exist, despite recognizing it

Hi. After doing a fresh install of VSCode and reinstalling PlatformIO, I am still unable to flash my Adafruit ESP32-S3 TFT Feather consistently or at all. At first it was issues with the chip not responding, or some error to do with the packet transfers, but it now has ultimately ended up with a COM port issue that I have no idea how to even begin to fix.

I get the following error:

A fatal error occurred: Could not open COM6, the port doesn't exist
*** [upload] Error 2

The thing that confuses me is that I am able to recognize the microcontroller through Device Manager, and through PlatformIO itself as being on the same COM port.

I am unable to interface with the microcontroller through PuTTY and get this:


Here are the contents of my .ini file:

platform = espressif32
board = adafruit_feather_esp32s3_tft
framework = arduino
lib_deps = 
	adafruit/Adafruit BNO055@^1.6.1

	adafruit/Adafruit MLX90393@^2.0.3
	adafruit/Adafruit ST7735 and ST7789 Library@^1.10.3

And here is what the entire terminal says for when I fail to upload to the ESP32 S3 TFT Feather:

Serial is working? There is no longer an issue with connecting to the microcontroller through PuTTY. However, the “COM port existing” issue still persists.
