Starship/Superheavy launch aborted at T-0; launch scrubbed

Starship/Superheavy today, just after engine abort
While all looked perfect right up until engine ignition at T-0 second in today’s attempt to fly the 13th test orbital flight of SpaceX’s Starship/Superheavy, the rocket then shut down, aborting the launch.
The company almost immediately announced they were scrubbing for the day, with a likely next attempt tomorrow though this is not confirmed.
This quick decision suggests the circumstances of the abort were such that they did not feel comfortable attempting a recycle and additional launch attempt. Mission control wanted more time to review the situation. At T-0 the engines did ignite for a second, so that might be why they wish to review things, to make sure the rocket is firmly on the pad and can be made safe for a later attempt.
Stay tuned for updates.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

How much of this could be tested ahead of time? Repeating the propellant load and the static fire until everything works, time after time.
Can they quickly try again (on the same day) after gushing out all that water?
Nope. Once they activate the deluge system, that’s it. It takes hours to re-fill all the tanks and get it ready again.
I want my money back for the excitement guarantee.
