I took a look at it.

#

You don't have >2 TWR. You think you do, and the engineer's report claims you do, but you don't. Reason: you're clipping your engines together, and as a result, most of them do not generate thrust in actual flight.

#

By ripping off all engines and all boosters and replacing them with something smaller and more sensible, I was able to get this thing to take off just fine with just 7 mammoths:

#

However, "take off just fine" is the limit of it. This rocket as it is will never make orbit. It is constructed with no regard for structural stability, and as a result, wobbles worse than cooked pasta. Additionally, the massive drag from the three hydrogen tanks flips it over before it gets even a third of the way to max-Q.

#

I'm afraid this isn't a case of "I need help to fix my rocket". This is a case of you needing to fundamentally rethink how you build stuff. If I were to "fix" this, I wager it would be unrecognizable as the same craft afterwards. Because nothing short of a full redesign will get this to orbit.
