MacOS issue: `get_browser_url()` crashes Tauri app when window is open or closed

[hoonweedev]

Hello, first of all I'd like to thank you for building this awesome project.

Currently I am building a Tauri app that retrieves user's browser url info every 1 second.
I am using x-win Rust crate in Tauri backend, and calling get_browser_url() to achieve this.

It works well at the beginning, but once I open a new app window or close an existing one, the tauri app crashes.

I'd like to know if I am using it wrong. Here's a code for getting url info every 1 second.

use std::time::Duration;
use tauri::{AppHandle, Emitter};
use x_win::{get_active_window, get_browser_url};

#[derive(serde::Serialize, Clone)]
pub struct ActiveAppInfo {
    desktop_app: String,
    web_app: String,
    timestamp: String,
}

#[tauri::command(async)]
pub fn start_app_monitor(app_handle: AppHandle) {
    loop {
        match get_active_window() {
            Ok(window) => match get_browser_url(&window) {
                Ok(url) => app_handle
                    .emit(
                        "active-app-info",
                        ActiveAppInfo {
                            desktop_app: window.info.name,
                            web_app: url,
                            timestamp: chrono::Local::now().to_rfc3339(),
                        },
                    )
                    .unwrap(),
                Err(_e) => app_handle
                    .emit(
                        "active-app-info",
                        ActiveAppInfo {
                            desktop_app: window.info.name,
                            web_app: String::from(""),
                            timestamp: chrono::Local::now().to_rfc3339(),
                        },
                    )
                    .unwrap(),
            },
            Err(_e) => app_handle
                .emit(
                    "active-app-info",
                    ActiveAppInfo {
                        desktop_app: String::from(""),
                        web_app: String::from(""),
                        timestamp: chrono::Local::now().to_rfc3339(),
                    },
                )
                .unwrap(),
        }

        std::thread::sleep(Duration::from_millis(1000));
    }
}
