Upgrading to Gradio v4 can solve this problem.

pip install --upgrade gradio

Upgrading to Gradio v4 can solve this problem.

pip install --upgrade gradio

But! no effect

I encountered the same issue under the same conditions, and the problem still persists even after I upgraded to gradio v4.

I'm also experiencing a similar problem.
Even after upgrading gradio, the issue is not resolved.
