“The flight was landing at a brand new airport that just opened on new years day.”
In looking at the aircraft in the still closer up pics, it looked like there were red flaps at the time the aircraft appeared to start to slide left into a stall. I listened to the narrator and he mentioned the original runway as 30 but that appeared to need a downwind landing.
I think the winds had a lot to do with it. They were flying over the Seti River Gorge area which has a history of wind variations as reported by the Nepal’s Civil Aviation Authority in 2019. And if they got a big fluctuation in wind direction or volume it could have caused the aircraft to lose lift and stall which the lifting of the nose displayed. And as said, they were so low, with flaps red and gear green, they couldn’t dip the nose to regain control.

That is good speculation. There are also foothills nearby that could funnel the wind into the gorge.
