USB-C port only works if an SD card is inserted at the same time
I have a 2021 Macbook Pro 16" M1 Max with Ventura 13.5.1 (22G90). The USB-C port next to the SD card slot only works when I inserted an SD card. As soon as I remove the SD card, the device is disconnected from the USB-C port at the same time. Does anyone have an idea why? (--> YouTube Video)
I have already run the Apple diagnostic program. This says everything is fine. Of course, I also restarted the Macbook several times and tested the port (unsuccessfully) with various USB-C devices. There is also no dirt in the USB-C port.
