Thanks for the follow-up! I saw that France did their own investigation, too.

The French BEA released a report in 2019 that said there were serious mechanical issues with the plane that weren't documented by pilots of previous flights, and the plane never should have been cleared for flight. They determined there was a fire in the cockpit caused by the Captain smoking, and a leaking oxygen mask creating an oxygen rich environment. The mask switch was set to Emergency which could leak to it leaking.
