1. 请提供最小可复现案例
2. 你需要仔细阅读这篇文章

[DehaiWang]

@thy486 我是按照 Quick Start 用的 cargo 和 yarn 的 两种方式， 并未写其他的代码，都尝试了，都是能出来窗口， 但是窗口中未显示内容，仅仅是白框。 我有两台笔记本，其中一台是windows10的能正常显示内容， 在 windows 11的那台笔记本上， http://localhost:1420 在浏览器上能正常显示内容， 但是在 cargo tauri dev 或者 yarn tauri dev 下都是空白的窗口界面。

Try modifying the registry:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\WebView2]
"RendererCodeIntegrityEnabled"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge]
"RendererCodeIntegrityEnabled"=dword:00000000

Refer to: https://github.com/l1xnan/jupyterlab-desktop/blob/main/src-tauri/src/main.rs#L43C1-L78C1

[DehaiWang]

@l1xnan sorry, not working, not find the Edge in "\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft"

[DehaiWang]

the code is

// Prevents additional console window on Windows in release, DO NOT REMOVE!!
#![cfg_attr(not(debug_assertions), windows_subsystem = "windows")]

// Learn more about Tauri commands at https://tauri.app/v1/guides/features/command
#[tauri::command]
fn greet(name: &str) -> String {
    format!("Hello, {}! You've been greeted from Rust!", name)
}

fn main() {
    tauri::Builder::default()
        .invoke_handler(tauri::generate_handler![greet])
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

just show blank , and the close button not work yet.

@l1xnan sorry, not working, not find the Edge in "\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft" !

The registry key does not exist by default. You need to manually add it

[DehaiWang]

@l1xnan after i add the registry keys, it still show blank . i try Compatibility mode，it works

[DehaiWang]

but one more question, when i code and rtauri dev in windows 11,it still show blank, how to do ?

@l1xnan after i add the registry keys, it still show blank . i try Compatibility mode，it works

The Compatibility mode is the only work solution for me.

I met the blank page problem with the simplest tauri example on Windows 10, and I searched for many solutions, only this reply saved my time... Thanks!
