So I have just unwrapped and installed my new Argon One case that I bought from a retailer over the internet. Everything went smooth... except it doesn't work. It just doesn't start up. When I press the power button, the red LED shortly blinks, but then everything is black again and the LED's don't light up anymore. I'm assuming that the case has trouble with the power supply as the fan also stays silent.
When I deconstruct it and power it via its own USB-C then it still works fine. My guess is that my GPIO pins must have been fried, because as I'm seeing it the case supplies power to the Pi via the 5V pin and prevents access to the Pi's own USB-C port. However, I never ever put anything even near the Pins, so i'm really confused.
