Link error when using actix-web and tokio

Question

I have a simple actix-web application (the example from the documentation) with actix-web and tokio as dependencies in Cargo.toml. Running cargo run give me this error:

error: linking with `x86_64-w64-mingw32-gcc` failed: exit code: 1

 = help: some `extern` functions couldn't be found; some native libraries may need to be installed or have their path specified
  = note: use the `-l` flag to specify native libraries to link
  = note: use the `cargo:rustc-link-lib` directive to specify the native libraries to link with Cargo (see https://doc.rust-lang.org/cargo/reference/build-scripts.html#cargorustc-link-libkindname)

From my research, I tried reinstalling cargo and updating the crates, but that didn't work. Running a hello world program works. I suspect the error is from the main function, as commenting that out and running the program does not error out. My code for reference:

#[allow(unused_imports)]
use actix_web::{web, App, HttpRequest, HttpServer, Responder};

#[allow(dead_code)]
async fn greet(req: HttpRequest) -> impl Responder {
    let name = req.match_info().get("name").unwrap_or("World");
    format!("Hello {}", name)
}

#[tokio::main]
async fn main() -> std::io::Result<()> {
    HttpServer::new(|| {
        App::new()
            .route("/", web::get().to(greet))
            .route("/{name}", web::get().to(greet))
    })
    .bind("127.0.0.1:8000")?
    .run()
    .await
}

My Cargo.toml file:

[package]
name = "proj_actix"
version = "0.1.0"
edition = "2021"

[dependencies]
actix-web = "4"
tokio = { version = "1", features = ["macros", "rt-multi-thread"] }

I also set my default toolchain as such: rustup default stable-x86_64-pc-windows-gnu (I had an error just after installing Rust, nothing was running but that fixed it). I'm on Windows 10.

What could be the problem here?
