mongo-rust-driver v2.1.0 compilation failure - mongodb

Question

rustc 1.60.0-nightly (17d29dcdc 2022-01-21) running on x86_64-pc-windows-msvc
I don't know how to solve, I deleted main to such an extent that it still reports an error
main.rs:
use std::error::Error;
#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
println!("Hello, world!");
Ok(())
}
error:
