Reproduction

import gradio as gr

with gr.Blocks() as demo:
    food_box = gr.Number(value=10, label="Food Count")
    status_box = gr.Textbox()

    def eat(food):
        if food > 0:
            return {food_box: food - 1, status_box: "full"}
        else:
            return {status_box: "hungry"}

    gr.Button("Eat").click(fn=eat,
                           inputs=food_box,
                           outputs=[food_box, status_box])

demo.launch()

Additionally, the same code works in gradio 5.4.0.

Hi @Col0ring I can't repro this with the latest version of Gradio. The provided repro works for me locally and on Colab: https://colab.research.google.com/drive/1BVtyY_TtSBnYZugjyNgCHAGP6yOA-i_w?usp=sharing

Did you run python app.py or gradio app.py? I found that only gradio app.py will cause this issue.

Weird, I can reproduce that!
