It looks like the plane couldn't properly take off(likely overloaded), and it's not just an overrun. See the speed graph in the post, and the fact that the gears were retracted that low.
I don’t think we have enough information to make that statement yet. Could be they forgot to set flaps, could be they miscalculated TO speeds, could be they misconfigured auto throttle...
As usual, need to wait for investigation and report.
