I was going to write a long reply about how to systematically do a board bring-up, but decided to write something a lot shorter.

Simply:

(1) Buy a second Arduino board (a lot cheaper than an oscilloscope, which is unessential for now) and use that to confirm if you have a board fault or not

(2) Use a second PC and second USB cable to confirm if you have a PC USB connection or cable issue

(3) Use the Arduino IDE (NOT Segger Embedded Studio) to run one of the example programs that are in the Arduino IDE, to confirm that software can run reliably

If (1), (2), (3) don't reveal any issues, then there's a great chance the problem lies in either your code, or the libraries or run-time you're linking together with, or your linker settings.

When an MCU gets reset, typically all I/O pins become inputs until the program starts, when the program may set them to be outputs. if your circuit allows current to flow through the LED when the MCU pin is an input, you could see it glow during the boot time. Can you post the schematic of your LED circuit?
