I want to use slint to make a dialog, but new slint meet problem

[Decodetalkers]

slint::include_modules!();

use std::sync::mpsc;

fn init_slots(ui: &AppWindow, sender: mpsc::Sender<bool>) {
    let global = ConfirmSlots::get(ui);
    let send_confirm = sender.clone();
    global.on_Reject(move || {
        let _ = sender.send(false);
        let _ = slint::quit_event_loop();
    });
    global.on_Confirm(move || {
        let _ = send_confirm.send(true);
        let _ = slint::quit_event_loop();
    });
}

pub fn confirmgui(title: String, information: String) -> bool {
    let ui = AppWindow::new().unwrap();
    ui.set_init_title(title.into());
    ui.set_information(information.into());
    let (sender, receiver) = mpsc::channel();
    init_slots(&ui, sender);
    receiver
        .recv_timeout(std::time::Duration::from_nanos(300))
        .unwrap_or_default()
}

this is my code, very time, I will use the confirmgui to make a new window and get the result, but after I update to the new version of slint, I found the second time enter the confirmgui, it failed, return error

called `Result::unwrap()` on an `Err` value: SetPlatformError(AlreadySet)

and because AppWindow contains UnsafeCell, I cannot use something like lazycell to make it static, then how to solve it?

What call to unwrap actually call this?
Are you trying to run the event loop twice in different thread? This is not supported at the moment.

code is here, it is in a dbus server, I want every time it enter some dbus function, I can create a window and do some selection,

yes, I init the event twice, so can thread_local fix it?
