Here is a self-contained reproducer, can probably be minimized further: playground link
trait Api: Sized {
type Device: ?Sized;
}
struct OpenDevice<A: Api>
where
A::Device: Sized,
{
device: A::Device,
queue: (),
}
trait Adapter {
type A: Api;
fn open() -> OpenDevice<Self::A>
where
<Self::A as Api>::Device: Sized;
}
struct ApiS;
impl Api for ApiS {
type Device = [u8];
}
impl<T> Adapter for T {
type A = ApiS;
fn open() -> OpenDevice<Self::A>
where
<Self::A as Api>::Device: Sized,
{
unreachable!()
}
}from rust.

@compiler-errors I'm not really sure how to minimize it. Currently, I have no idea which struct is causing the error, nor why. I have tried using cargo-minimize, but it did do very much at all. Let me know if there's something else I should try.
P.S. the scope of the changes isn't too huge, and I'm 100% sure that the issue relates to the new ?Sized bounds on Api types.

Alright I may have actually just found it. It seems like it's in this struct:
pub struct OpenDevice<A: Api>
where
A::Device: Sized,
A::Queue: Sized,
{
pub device: A::Device,
pub queue: A::Queue,
}from rust.

@lukas-code thank you very much. I was gone else I would've done that myself 😅.
