C3422WE, #5 USB-C/DP upstream stops working

From one day to another, the USB-C port (number #5) on my C3422WE went 'dead'; no more power, no internet, no keyboard, no screen, etc. It did not detect any hardware connected to it.

I have tried with two laptops: One running on Windows 10 and one on Windows 11. I have used the original 1m DELL cable and two other cables, of which one is certified for 100W pass-through.
