Could you provide some information for helping the investigation:

• The complete reproduction steps. Note that you provide a git clone without pinning to a commit. That may introduce uncertainty when reproducing it.
• The actual errro output you got.
• The way you installed the Rust toolchain. And where is the cargo executable located.

@weihanglo I have updated the steps. rust is installed through homebrew,

brew install rust

and the location looks like /usr/local/Cellar/rust.

On the same condition but 1.81 looks like working and so please ignore this.
