KT2 pro error (link to video)

I am attaching a link to a video I shot myself.

It’s been 10 days since I bought it.
There was no problem right after the firmware update 3 days ago.
A sudden error from today.

  1. Constant popping sound from connected headphones.
  2. The drive is not recognized by the computer.
  3. Sufficient power is being supplied.
  4. I changed the cable, but there is no change.
  5. I tried reinstalling the drive, but there was no change.

@Eric68, @Gouwa,
