这个错误是由于Blazor组件在渲染时尝试添加addEventListener时引发的，但是该组件尚未完全加载并存在于DOM中，因此无法添加事件侦听器。为了解决这个问题，您可以在组件加载后才添加事件侦听器。以下是示例代码：

1. 创建一个组件基类来处理事件侦听器的添加和删除

public class EventComponent : ComponentBase, IDisposable
{
    private readonly Dictionary> _eventCallbacks = new ();

    protected void AddEventListener(string eventName, EventCallback eventCallback)
    {
        if (_eventCallbacks.ContainsKey(eventName))
        {
            _eventCallbacks[eventName] = eventCallback;
        }
        else
        {
            _eventCallbacks.Add(eventName, eventCallback);
        }

        if (IsEventTargetReady())
        {
            AddEventListenerImpl(eventName);
        }
    }

    protected void RemoveEventListener(string eventName)
    {
        _eventCallbacks.Remove(eventName);
        RemoveEventListenerImpl(eventName);
    }

    protected virtual void AddEventListenerImpl(string eventName)
    {
        // Implement the event listener attach logic in a derived class
    }

    protected virtual void RemoveEventListenerImpl(string eventName)
    {
        // Implement the event listener remove logic in a derived class
    }

    protected virtual bool IsEventTargetReady()
    {
        // Implement the check if the event target is ready in a derived class
        return true;
    }

    protected void RaiseEvent(string eventName, EventArgs args)
    {
        if (_eventCallbacks.TryGetValue(eventName, out var callback))
        {
            callback.InvokeAsync(args);
        }
    }

    public void Dispose()
    {
        foreach (var eventName in _eventCallbacks.Keys)
        {
            RemoveEventListenerImpl(eventName);
        }
    }
}

2. 创建一个继承自EventComponent的组件，并覆盖AddEventListenerImpl和RemoveEventListenerImpl方法

public class MyComponent : EventComponent
{
    private ElementReference _elementRef;

    protected override void AddEventListenerImpl(string eventName)
    {
        _elementRef.Value?.AddEventListener(eventName, CreateEventCallback(eventName));
    }

    protected override void RemoveEventListenerImpl(string eventName)
    {
        _elementRef.Value?.RemoveEventListener(eventName, CreateEventCallback(eventName));
    }

    protected override bool IsEventTargetReady()
    {
        return _elementRef.Id != null;
    }

    private EventCallback CreateEventCallback(string eventName)
    {
        return EventCallback.Factory.Create(this, args =>
        {
            RaiseEvent(eventName, args);
        });
    }
}

3. 在组件中使用AddEventListener和
