when the rocket started leaking propellant after reaching space

Oxygen or methane?

The final mishap report cites the probable root cause for the loss of the Starship vehicle as a failure of a fuel component.

Oxygen or methane?

How much?...

Perhaps if you had read just a little further into the article you would have discovered the answers to your questions that were presented there.

Oh you mean this paragraph?

The rocket compensated for the drop in main tank pressure and completed its engine burn, but venting from the nose cone and a worsening fuel leak overwhelmed Starship's attitude control system. Finally, detecting a major problem, Starship triggered automatic onboard commands to vent all remaining propellant into space and "passivate" itself before an unguided reentry over the Indian Ocean, prematurely ending the test flight.

Nowhere do I see what exactly was leaked or how much. If we're using rocket terminology 'propellant' means methane, oxidizer means oxygen so I'm guessing they mean methane? Why doesn't the article say it was methane and couch it behind terminology? How much 'substance' was 'vented'?

Perhaps you could quote the part where they specify what the leak was and how much?
