hii @ogoffart this log in the code assert_eq!(self.0.get(), local.map_or(null(), |v| v.get_ref() as *const BindingHolder)); line 323, column 13, when i call api get data and update UI with code auto nodelists = std::make_shared<slint::VectorModel<INode>>(nodes); ui->set_NodeIndex(0); auto node = nodes[0]; ui->set_Node(node); ui->set_ListNodeEnabel(nodelists); and code slint::invoke_from_event_loop([&, ui = slint::ComponentWeakHandle(ui)] { auto ui_lock = *ui.lock(); ui_lock->fn_HandleBlockScreen(false); // end ui }); the log happen and i can't call api anymore

The issue is happening because you are using Slint from different task.
You should dedicate one task to Slint and do all the call to Slint function in that task only.
The only function you can call from another task is slint::invoke_from_event_loop (or the blocking version)

Thank you for reply but Plss clearly that, I create ui in app_main() like // create ui static slint::ComponentHandle<AppWindow> ui = AppWindow::create(); and I use ui variable in different tasks are unreasonable?

Hii @ogoffart I just use ui->set_... in Task READER another Task I use slint::invoke_from_event_loop([&, ui = slint::ComponentWeakHandle(ui)] { auto ui_lock = *ui.lock(); ui_lock->set_Notification(1); // end event }); like u say but issue still happen
