Description
I tried this code:
fn main() {
let path = std::path::Path::new("");
if let Err(err) = path.canonicalize() {
println!("{}", err);
// println!("{:?}", err.kind());
}
}I expected to see this happen: canonicalize() returns os error 3 (ERROR_PATH_NOT_FOUND)
Instead, this happened: it returns os error 123 (ERROR_INVALID_NAME)
This is problematic as std::io::ErrorKind doesn't become NotFound but Uncategorized, which isn't useful for most users. Other platforms like Linux return NotFound so the former behavior should be correct here.

The issue doesn't happen on rustc 1.58.0-nightly (e99963c55 2021-10-29), I think the regression was introduced by #89174.
