The views from Ship's engine bay looked rather ominous -- with the red glow visible in multiple places, and something venting furiously from the broken engine. It was a pleasant surprise that the ship did not explode and not only that, but it even landed exactly on target. Guidance system software engineers have done a very good job! The booster not completing the return part of the flight was disappointing. They had a similar incident in one of the previous flights, when they tried to maneuver the booster too aggressively immediately after stage separation which caused problems with the fuel supply. If it was something similar this time, it might be solvable by changing just a few details of the maneuver. So, maybe it is not that huge of a deal. There were many cool things in the webcast, from them showing the catamarans that are deployed at the landing site, to the views form the cameras on-board of the "satellites". The first few minutes after liftoff were just amazing visually. |

Scott Manley goes into quite a bit of detail on analyzing superheavy’s failed boostback, it’s a good watch:

TL;DR - seems like the hot staging kicked the booster out in the wrong direction, and the ship’s plume impacted one of the grid fins, which would’ve given it quite a big kick. The sloshing just from that could easily have caused the observed issues.
