Drone fell from 30 meters in auto mission, i cant see errors in log

After a many day without problems, in a fligth the drone fell from 30m. I cant find errors on tlog, log, and mavlink(battery, motors, desired pitch and roll, it was okay). What could have happened?

Thanks for help!

Unfortunately you disabled some useful logging data. I would suggest setting the log bitmask back to default.
You are running old software on mostly default parameters. Even the Initial Parameter Setup was not done which is a pre-1st flight process. And the parameters that were changed don’t make a lot of sense. The Rate Pitch/Roll I term is typically either equal to P or slightly below. Not an order of magnitude. Hence the tuning looks poor. If you do piece this back together you need to start from step 1.

Just before it took a dive to the earth it shows a Mission 1 Takeoff command. Not sure what happened there.

Looks like it thought it was landed and then disarmed around WP58 at 30m AGL.
The radios failsafes are worrisome too.
