I had the exact problem on KC868-A6 using MacBook Air with M3 chip. Tried multiple USB-C cables unsuccessfully. The only thing which would work is an old USB-C to USB-A cable connected to a USB-A to USB-C adapter, then plugged into the Mac USB-C port. Using the Mac to other USB-Serial boards with CH34x chips and the same USB-3 to USB-3 cables did not have a problem. Its only an issue with connection to the KC868-A6 CH340C serial circuit.
