Your issue lacks a bit of information and also seems to be more an issue related to rayon rather than bulletproofs, but I'll try to help.

It looks like you are trying to use bulletproofs with rayon in your custom project, which version of Rustc are you using (rayon 1.6.1 requires rustc version 1.56+)? Try to run rustup update.

Hey,
the issue seems to be related Rust version described in the toolchain and supported by the bulletproofs main branch.
syn 2.0.15 requires version 1.56.
There are some PRs open / forks that fix such issues (one from our team actually).
