proc macro [name] not expanded: Failed to run proc-macro server from path

This error is being highlighted in my code and I don't know what it is

proc macro '[name]' not expanded: Failed to run proc-macro server from path /Users/ruan/.rustup/toolchains/stable-aarch64-apple-darwin

Haven't found anything about this specific path error. What could it be?

I have already installed rust-analyzer and updated it, and the path doesn't require any special permission.
