Hi,
I'm new to Arduino programming and am undertaking a project using a NodeMCU board.
I am having trouble uploading a sketch to my NodeMCU board. I have had previous success uploading the same sketch to the board, but seemingly without changing anything, the board gives me the following verbose error:
Arduino: 1.8.7 (Windows Store 1.8.15.0) (Windows 10), Board: "NodeMCU 0.9 (ESP-12 Module), 80 MHz, Flash, 4M (1M SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 9600"
Sketch uses 296336 bytes (28%) of program storage space. Maximum is 1044464 bytes.
Global variables use 31696 bytes (38%) of dynamic memory, leaving 50224 bytes for local variables. Maximum is 81920 bytes.

It seems whenever I hold down the FLASH button while plugging the board in, the error reads as such (non-verbose):
Arduino: 1.8.7 (Windows Store 1.8.15.0) (Windows 10), Board: "NodeMCU 0.9 (ESP-12 Module), 80 MHz, Flash, 4M (1M SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 9600"

The main difference being that the board is actually attempting to upload the sketch.
Does anyone have any idea why this is happening? Is the board faulty?
I have the proper USB firmware. I've tried varying the upload speed. I've had success previously with 57600. I've tried varying the board selection in the IDE as well.
I've attached a picture of the board (pin D8 is missing).
Any recommendations would be appreciated. Thank you.
