It's unlikely to work unless the button is so reliable that you have a better chance of winning the lottery than the button/mechanism failing in some (possibly undetectable) way. It's the same argument against trying to use quantum immortality to force a miracle by killing yourself, or constructing a machine to kill you, unless some desirable event occurs. It's much more likely that your machine will fail, or you'll change your mind.

We could imagine that the simulation naturally backtracks given a paradox or dead end. So if the lottery is rigged, I would never get rich, and the simulation would just backtrack to where I would never decide to try this.

The mechanism by which you construct that paradox would still be a mechanism that can fail, just (presumably) not a mechanical one.
