Async function calls crashing app

[Enduriel]

Thank you for working on this project, I hope I can get it working because this would be perfect for our use case.

I've created a test example project following the guidance here, with a basic test component that performs an action on button click.

I'm running off the main branch with a single commit to disable the RUSTFLAGS override, as with the main release I was getting a differ, and using react native 0.81.1 with uniffi 0.29.

I added these functions for basic testing to my main crate

#[cfg_attr(feature = "uniffi", uniffi::export)]
pub fn foo() -> String {
	log::info!("foo called");
	"bar".to_string()
}

#[cfg_attr(feature = "uniffi", uniffi::export)]
pub async fn foobar() -> String {
	log::info!("foobar called");
	"foorbar".to_string()
}

and I have a basic testing component that executes this code when I click a button

console.log('Executing login...');
const result1 = foo();
console.log('Foo result:', result1);
const result2 = await foobar();
console.log('Foobar result:', result2);

foo() is executed perfectly, but the moment I await foobar either on IOS or android, it crashes with very little to go off of in the log: ios android.

Please let me know if I'm missing something or if there's something else you'd like me to try, I would appreciate any help because I really am not sure what to do here.

Once again thank you for your work here.

The core of this issue seems to be that my error struct was called Error and the rename to Exception was not being correctly handled in the uniffi bindgen react native crate. Here's a minimal example that causes the crash:

uniffi::setup_scaffolding!();

#[uniffi::export]
pub fn foo() -> String {
    "bar".to_string()
}

#[uniffi::export]
pub async fn foobar() -> String {
    "foobar".to_string()
}

#[derive(uniffi::Object)]
// pub struct Error1 {}
pub struct Error {}

renaming Error to Error1 makes everything work fine
