Failed to unregister class Chrome_WidgetWin_0. Error = 0

[justintaylor-dev]

Trying this plugin with a fresh Tauri Svelte-TS project. Saw in the issues that we should use 0.1.3 until Tauri 1.1 comes out, but still having this issue:

thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', src\main.rs:17:48
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

fn main() {
    tauri::Builder::default()
        .setup(|app| {
            let window = app.get_window("app").unwrap();

            #[cfg(target_os = "macos")]
            apply_vibrancy(&window, NSVisualEffectMaterial::HudWindow)
                .expect("Unsupported platform! 'apply_vibrancy' is only supported on macOS");

            Ok(())
        })

let window = app.get_window("app").unwrap(); that should be let window = app.get_window("main").unwrap();
