note: the compiler unexpectedly panicked. this is a bug.

For what it's worth, I can reproduce this issue with rustc version 1.63.0, but it doesn't happen with 1.64.0 nor with the latest stable version 1.66.0.

Here is it minified, and standalone-ed:

use std::{future::Future, marker::PhantomData};

fn spawn<T>(future: T) -> PhantomData<T::Output>
where
    T: Future,
{
    loop {}
}

#[derive(Debug)]
struct IncomingServer {}
impl IncomingServer {
    async fn connection_handler(handler: impl Sized) -> Result<Ok, std::io::Error> {
        loop {}
    }
    async fn spawn(&self, request_handler: impl Sized) {
        async move {
            spawn(Self::connection_handler(&request_handler));
        };

Triage: This has been fixed on the latest nightly, as reported, and needs a test to close.
