Interesting - I've only seen this once before. The txt log is quite badly corrupted, but fixable, and the downlink was solid until the log stops. I see a couple of possibilities, the first being interference from the microwave array adjacent to the flight path. But disregarding the errors in the log file, the most notable feature is that the log ends immediately after the elevator is centered from full forwards, which causes a sudden positive pitch excursion.

If that were the case then the aircraft will have shut down or rebooted, and crashed. Based on its final velocity and height, and taking wind into account, that gives a predicted descent path as shown below in green:

Looks like it might have made it beyond the trees into that cleared area, so maybe worth a look.
