Hello !
I'm a fair beginner in Rust, so it could that I'm just a bit silly. None the less, the compiler said it would appreciate a bug report so here goes below. In my minimization I have removed anything that has to do with Serialization.

I did notice that using the latest nightly, the error now moves into a normal compiler error. So it might have been solved but I failed to find the issue that would relate to it.

Thanks all!

A smaller example with no external dependencies

enum Schema {}
struct ObjectBuilder;

impl ObjectBuilder {
    pub fn property<S, I: Into<RefOr<Schema>>>(self, property_name: S, component: I) {}
}

error: could not compile `playground` (bin "playground")

ICEs on stable 1.79.0. Produces a normal error on nightly (2024-06-24 6b0f4b5).

Probably a duplicate of #126129.
