No response after clicking button

Describe the bug

I am running a project cloned from GitHub. The project code tries to execute a function when clicking the Gradio button, but the function is not executed when it is actually run. After multiple troubleshooting, I tried to copy a demo code from the Gradio official website to run it, the code similar to the following. When I ran it, I found that the function was not executed and there was no output in the console. I tried to upgrade/downgrade my Gradio version, but the result was the same. This looks like a bug. What should I do to make this function execute correctly?

code：

import gradio as gr

def greet(name):
    print("1111111111111")
    return "Hello " + name + "!"

with gr.Blocks() as demo:
    name = gr.Textbox(label="Name")
    output = gr.Textbox(label="Output Box")
    greet_btn = gr.Button("Greet")
    greet_btn.click(fn=greet, inputs=name, outputs=output, api_name="greet")

demo.launch()
