Матурин не собирается из-за Cargo, вот ошибка:
error: `cargo build --manifest-path Cargo.toml --message-format=json-render-diagnostics --release -v --locked` failed with code 101
Если глянуть выше, то:
cargo build --manifest-path Cargo.toml --message-format=json-render-diagnostics --release -v --locked

this Cargo does not support nightly features, but if you
switch to nightly channel you can add
`cargo-features = ["rust-version"]` to enable this feature
