[bug] Exception in creating a new window under Windows

[handexing]

Describe the bug

It's normal on Mac systems, but on Windows systems, when I click a button to create a new window, a blank page always appears。

Reproduction

#[tauri::command]
async fn open_pet_window(app: tauri::AppHandle) {
   use tauri::webview::{NewWindowResponse, WebviewWindowBuilder};
   let webview_window = tauri::WebviewWindowBuilder::new(&app.clone(), "label", tauri::WebviewUrl::App("mango_pet.html".into()))
       .build()
       .unwrap();
}

Expected behavior

Under the Mac system

Hmm, usually it's https://docs.rs/tauri/latest/tauri/webview/struct.WebviewWindowBuilder.html#known-issues but you're already using an async command 🤔

Can you share the config or builder of your other open windows? Some configs can conflict across windows on Windows.

@FabianLars I upgraded Tauri to the latest version and now there are no issues. Thank you
