I am not sure if I am able to solve this ICE -- it has to do with the way that async fn in traits are treated as async fn in some places, but not lowered as async fn in other places. That means there's a DefId that is not associated with a HIR Id, but I can't exactly track it down.

I'm working on a return position impl traits change that is going to make it easier to lowering return position impl traits in traits and that would make async fns in traits easy. All this is in my todo list. I should be able to accomplish some of these things soon.

@cjgillot not sure if you were going to work on this, but we can talk about this in Zulip if you want.

Triage: The ICE doesn't occur on the latest nightly, bisecting shows #97694 fixed it but I'm not 100% sure what PR did, perhaps #97471? Marking E-needs-test.
