One of the challenges with solipsism or any claim about metaphysics is that we lack access to evidence to settle disputes about it (once we steelman what we mean say it’s not obviously false). In this sense, it’s something we can imagine but cannot justify. Same goes for alternatives to solipsism, like physicalism.
So there’s not much to say here. You can’t prove it disprove solipsism by our normal epistemological methods because it hinges on information we can’t have.
