Thanks for the video. I worked out that the LED_BUILTIN macro wasn't resolving to the correct pin number (which for my board is 13). Turns out I had the wrong board type selected in the IDE, and once I fixed that, the macro resolved to 13 as expected and the LED started flashing properly.
At 4:43, you have the LED wire in socket 12, not socket 13. So why is the LED still blinking? A few frames later I see that the wire is back in socket 13.

You are welcome.

Good eye. At one point I was using pin 12 in my code, but changed to pin 13 to match the LED_BUILTIN define, but still used old video footage. 😁
