I am getting like the error above. when I use opessl crate with vendored feature, this error is throwen by rust-analyzer. It may be related to proc_macro's. But I am not sure. Using Windows 11. cargo version 1.80.0

With the latest version this error has been downgraded to a debug log. If there's anything else wrong with your rust-analyzer workflow, this is not the cause.
