Sounds suspiciously like a short in the actual connector going to the GPIO pins. If you haven't connected the other end to a breadboard all you doing is extending the actual GPIO pins so any reading should be the same with or without the ribbon cable connector at the Rock64 board. Try a different cable just to rule it out.

Have you tested voltages at the GPIO pins with and without the ribbon cable attached.
