It looks like you had a constant compass error during the whole flight. When was the last time it was calibrated? It is possible you took off from a highly magnetic area near iron and once it was clear of interference it registered a constantly upset compass reading. You probably should have landed immediately and investigated and addressed the problem.
I notice you took off with the battery showing 67%, and the voltage per cell quickly drops over a few seconds from 3.9 to 3.4 volts, merely from a brief ascent. This looks like you were using a previously used battery and did not charge it fully before flight, which is a no-no. Re-using partially used batteries results in unreliably estimated battery capacity, and may result in unexpected shutdowns.
It was flown for about a minute with the battery cells dipping into low levels of around 3.2V. It then went into GoHome mode. The aircraft lost telemetry after about 6 seconds, and resumed about 30 seconds later. It indicated it was in Autolanding mode, presumably from being in loss of contact with the controller. The roll value indicates the aircraft was upside-down. There was no GPS signal (expected when the GPS receiver in the top centre of the frame is obscured from the sky whilst upside down). The last location recorded by the GPS was 34.91060865, 33.63725869. I assume it crashed and was recovered here? It is unclear from your post. It appears you did a CSC to turn it off after recovery at around 2 minutes. The data indicates you were at an altitude of 2000 - 3000 ft below your takeoff point, which is incorrect, and may have been influenced by your constant compass errors.
If it's still under warranty, you could ask DJI to take a look at your flight record for you, I don't know if they can make anything more out of it. I'm not sure what sort of claim you want to make. What happened that you didn't expect or can't explain? A better description in the original post would help determine what you need help with or are uncertain about.
