InvalidOperationException: The following game object is invoking the DontDestroyOnLoad method: WXSDKManagerHandler. Notice that DontDestroyOnLoad can only be used in play mode and, as such, cannot be part of an editor script.

这个错误通常是由于在编辑器模式下调用了DontDestroyOnLoad方法，而该方法只能在运行时使用。你可以通过在代码中添加条件语句来避免这个错误，例如：

#if UNITY_EDITOR
    // 在编辑器模式下不执行DontDestroyOnLoad方法
#else
    // 在运行时执行DontDestroyOnLoad方法
    DontDestroyOnLoad(gameObject);
#endif

这样就可以在编辑器模式下避免调用DontDestroyOnLoad方法，从而防止这个错误的出现。

An unhandled exception occurred while processing the request. InvalidOperationException: JavaScript interop calls cannot be issued at this time. This is because the component is being statically rendered. When prerendering is enabled, JavaScript interop calls can only be performed during the OnAfterRenderAsync lifecycle method.

这个错误通常发生在Blazor组件在静态渲染期间尝试执行JSInterop调用时。由于在静态渲染期间不支持执行JavaScript交互操作，因此会出现这个错误。

为了解决这个问题，你可以将JSInterop调用移动到`OnAfterRenderAsync`生命周期方法中。这样，在组件渲染完成之后才会执行JSInterop调用。以下是一个示例：

protected override async Task OnAfterRenderAsync(bool firstRender)
{
    if (firstRender)
    {
        var cookieValue = await JSRuntime.InvokeAsync<string>("getCookieValue", "kaoshi90");
        // 执行其他操作，如更新组件的状态等
    }
}

在上面的代码中，我们使用了`firstRender`参数来确保JSInterop调用只在组件首次渲染时执行一次。

确保在`OnAfterRenderAsync`方法中进行JSInterop调用之前，将JavaScript文件引用到Blazor的index.html文件中。

通过将JSInterop调用放在适当的生命周期方法中，你应该能够避免在静态渲染期间发生JavaScript交互调用的错误。

InvalidOperationException: Cannot Open when State is Open.

The error message "InvalidOperationException: Cannot Open when State is Open" typically occurs when you try to open a connection to a database that is already open.

To fix this issue, you should first check if the connection is already open before attempting to open it again. You can do this by calling the "State" property of the connection object, which will return the current state of the connection.

For example, you can check if the connection is open like this:

if (connection.State == ConnectionState.Open)
{
    // Connection is already open, do not attempt to open again
}
else
{
    // Connection is not open, open it now
    connection.Open();
}

Make sure to always close the connection when you are finished using it, to avoid this issue in the future.
