Because of the snow and the icy fog,
On one of the pictures you can see that the prop picked up some ice. Maybe this has an adverse effect on the efficiency of the prop, requiring a higher power input from the motor. Maybe this contributes to the over-temp of the ESC.
Very interesting project.

The motor consumption during the climb was about 200W, draining 20 to 30 Amps, which is fine for the speed controllers we have selected as long as they are cooled by the airflow. Because of the snow and the icy fog, we had to close all the air inlets to protect the electronic boards, thinking that an outside temperature between 0 and -10 would be enough.
