You took off with a brand new battery at 64%.
And it looks like you flew really hard against winds aloft.
It is always best especially if flying far to take off with a full battery.
Also, I know DJI does not document this, but I like to break in Lipos gently by not flying full power or below 50% on the first 10 flights or so. This helps to make the Lipo last longer. I also like to never charge above 1C on the first 10 charges or so, this is moot as DJI does the charge rate, not a smart charger.
I also like to make the first batch of flights close and over a field or lawn, just to break in a new battery and in case there is a problem with the Lipo. Lipos are complex and need care. I know DJI is trying to take the complexity out of flying MRs, but a Lipo is still a Lipo. I think for DJI is doing a good job making this hobby simpler, easier to learn and safer. But if you have flown a lot with Lipos there are some good procedure to follow conditioning them when new. And a few tricks to storage etc.
Here is a link to info about Lipos:
Understanding RC LiPo Batteries
My guess is the battery malfunctioned and for some reason just cut all power. That is what it looks like. Or it fell out, I can see this if it was not clicked in and the MR was bucking gusty wind. A bird strike is also possible.
