Yeah, wasmtime-wit-bindgen no longer uses async_trait as of https://github.com/bytecodealliance/wasmtime/pull/9867, so application code will need to be updated to match.
The hope is that you "just" remove #[async_trait] and you're good to go, but I haven't updated anything myself yet to double-check that's the case
Can confirm removing #[async_trait] from the bindgen Host impls works :+1:
Thanks
