Why in the VSTO development Excel AddIn environment, the "Refresh All" button clicked by Excel will cause the Click event of the custom CommandBarButton to fail?

Question

为什么在 VSTO 开发 Excel AddIn 环境中, Excel 点击的 “数据” > "数据和连接" > “全部刷新” 按键会导致自定义 CommandBarButton 的 Click 事件失效？

在不点击 “数据” > "数据和连接" > “全部刷新” 按键的情况下，自定义 CommandBarButton 的 Click 是会一直生效的。

下面是我创建 CommandBar 的代码：

Translated from Chinese to English:

Why does Excel click "Data"> "Data and Connection"> "Refresh All" in the VSTO development Excel AddIn environment, which will cause the Click event of the custom CommandBarButton to fail?

Without clicking the "Data"> "Data and Connection"> "Refresh All" button, the Click of the custom CommandBarButton will always take effect.

Here is my code to create the CommandBar:
