Help me understand what happened here: hard crash due to DJI NFZ causing aircraft lose of control and hit tree

https://mavicpilots.com/threads/help-me-understand-what-happened-here-hard-crash-due-to-dji-nfz-causing-aircraft-lose-of-control-and-hit-tree.97094/

So I was flying the other day in an area that has no other NFZ restrictions other than an altitude restriction of 150 meters. Right as I'm about to come in for a landing, the Mavic 2 seems to have a mind of its own, and basically flew a horizontal track at immense speed across the field and struck a tree at high speed before crashing to the ground causing damage to the foot and the battery completely popped out in the process.

Why did it do this instead of coming straight down or allowing me time to land it myself? I was handflying it and taking pictures and it was clear day, perfect weather, no winds, and everything was fine (got full GPS lock etc) no obstructions and wasn't flying near buildings or anything and then it started complaining about entering no fly zone, however where I'm at it was an altitude restriction and I was flying WELL UNDER the 150 meter restriction so that shouldnn't have even been a factor or point of contentionn at all...

In any case, what caused the crash was the Mavic going crazy and suddenly decided to basically track horiztonally on the ground at high speed until it struck a tree...

Later I tried to get export of the logs from the aircraft itself but I tried on Windows 7 machine, and two different Windows 10 machines, and all were brand new installs of the latest DJI Assistant app (for desktop PC) for the Mavic 2 version (I also tried the generic old DJI Assistant 2 app etc) but it will just spin and spin and not ever actually show me any logs to even allow me to export to provide to DJI.

I know these logs on the aircraft are encrypted but I should at least be able to export them to send to DJI upon request and its not even letting me do that!
