Is this possible, or just a nonsense concept?

Boltzmann Brains are thought to be possible due to quantum fluxuations in an eternally inflating model of the universe, if true means that brains can spontaneously appear (although so rarely that it only makes sense to talk about them on infinite time/space scales).

That being the case, wouldn't that make Solopsism possible in a material reality (including this one), given a sufficiently sophisticated Boltzmann Brain?

No, because Solipsism is the view that only one's mind exists and its contents (there is nothing outside of this mind). However, if this mind fluctuated into existence from a physical background, then that physical background obviously exists. Thus, it wouldn't be the case that Solipsism could be true, as there would be more to existence than just that one mind and its contents; the physical background itself.

Solipsism is a nonsense concept. Suppose your mind is all that exists. What has that told you? What have you learned about your world? Answer: Nothing whatsoever. It's a meaningless, bullsh*t concept that provides no information about anything, and serves only to give Philosophy students an excuse to sound deep.

Well solipsism is metaphysically possible anyway, regardless of the Boltzmann Brain possiblity. There's just no reason to think that it's plausible, however.
The argument is used to deny the plausiblity of the multiverse, not to affirm solipsism. By that, i mean that solipsism doesn't immediately follow as an implication. You'd first have to find it plausible that you are, in fact, a Boltzmann Brain. To do that, you'd have to first address other issues regarding multiverse theory, then build a case supporting the plausibility of the multiverse. Even then, there's no reason to think you are a Boltzmann Brain rather than a real embodied entity existing in a real material world. After all, on the multiverse theory, assuming an infinite amount of universes, both being in a real material world, and being a Boltzmann brain are just as actual.
I think Occam's razor would have you trust current cosmology rather than postulating additional circumstances to arrive at the same conclusion, namely, the observed world.
When it comes to rational belief, it comes down to plausibility, not just possibility.
