It seems that Starship, the second stage, experienced RUD from the automated FTS at around the time it was expected to shut off its engines.
Edit: RUD is Rapid Unscheduled Disassembly. Basically an explosion. FTS is Flight Termination System, which explodes a rocket if something goes wrong in a potentially dangerous way.
