Nobody is trying to land humans on the reusable part of the rocket, this is the first stage returning under power. There is no elephant in the room, there is no room and no elephant either, so a lack of data is the expectation, not something worth mentioning.

Spacex plans to land humans on a reusable part of the rocket with the stardip.

Stardip?

They also plan to make a trip to Mars.

SpaceX has a lot of stuff on the drawing board and may or may not execute on any of that. For now what you have is a two stage to orbit vehicle that can be topped with a man rated capsule.

Good old 'parachute & splashdown'.

Starship is - for now - mostly fiction with some parts under test, if and when they plan to do their second stage controlled and re-usable landings you can be sure there have been very large numbers of landings without mishap or SpaceX will blow all their credit in one RUD.

So let's wait until it is 'on topic' before spouting off, there are plenty of possible reasons why this landing could have been aborted, a very large number of those possible reasons hinge on the state of the drone ship (platform stability, for instance) which might have worked just fine if the landing had been attempted over land on a pad.
