Potentially gear issues on first landing, RAT may give that away at the moment. I think the possibility that there was some terrain contact with the engines slightly followed by a go around. But unsure on the final approach that resulted in the crash. By looking at the CCTV clips both engines are out as the crew are attempting to max out the lift with the high AoA.
Could have had a genuine fault with the gear followed by a depletion of fuel on the go around...
