code snippet to reproduce:

#[derive(Default)]
struct OptionOwned<T: ToOwned> {
    owned: Option<T::Owned>,
}

Use Convert to manual `impl Default for OptionOwned` on Default:

impl<T: ToOwned + Default> Default for OptionOwned<T> {
    fn default() -> Self {
        Self { owned: Default::default() }
    }
}

Use rust-analyzer.expandMacro on Default:

impl<T: core::default::Default> core::default::Default for OptionOwned<T>
where
    T: ToOwned,
    T::Owned: core::default::Default,
{
    fn default() -> Self {
        OptionOwned {
            owned: core::default::Default::default(),
        }
    }
}
