Hello friends, today I experienced a failure during the flight of my multicopter, around minute 7:52, I lost control of the multicopter and it went into loiter mode, then land mode. I had to activate return to home in the radio control station and being closer I was able to regain control without any problem, I still don’t know the cause, in principle the failsafe should automatically activate the return mode, so I have configured and tested it by turning off the station. In the logs, I can see that many things have been recorded and surely the explanation is there, I can see that there was interference with the gps, can someone with more experience see something else? The max speed values are wrong in the logs, It was a slow flight.

Here is the flight log and details
