What would have changed if Werner Heisenberg had not deliberately sabotaged the German nuclear arms program by introducing a subtle mathematical error into his equations?
Deliberately? That is ‘not certain’, see here.
The ‘Atomkeller’ in Haigerloch is the place where the germans did their experiments:

Compare this with Fermi’s test reactor:

If you could understand german, here is an interesting link. In the first paragraph is described how Heisenberg reaches the first chain reaction in 1945. And he was glad it stopped because they had no security measures.
And the Nazi never took the bomb very serious. Otherwise they would have spend much more effort in it.

I warn you my German reading and writing abilities are grade school level, but I think I got the spirit of the thing:
Haigerloch, 1945
A not-good feeling disturbed W. Heisenberg and K. Wirtz -
they didn’t know how to stop an atomic chain reaction.
Difficulties with the security . . . {whatever… lost me there.
Well I went back and basically there was no security and it scared the scientist…
but crist it was middle Nazi German, before the public knew what an atom was.}
Then there was a little kink in the curve, the reaction didn’t happen.
The team of physicists around W.H & K.W breathed a sigh - while being simultaneously much disappointed.
Their goal, the first nuclear reactor pile failed.
Don’t you just gotta love that second sentence
And I’m sure I got that right:
“Ein ungutes Gefühl beschleicht Werner Heisenberg unf Karl Wirtz - sie wissen nicht, wie eine unkontrollierte Atomkettenreaktion zu stoppen wäre.”
