Gr.load doesn't work with Blocks app

Hi there, I used gr.load method to load a Interface gradio app successfully.
However, when I use gr.load to load a Blocks gradio app, it returned “runntime error” as below. I am sure the Blocks gradio app run well. What’s wrong with it?

Traceback (most recent call last):
