There doesn’t seem to be an exact duplicate issue (there are many issues where errors occur in Gradio). Personally, I suspect that something may have gone wrong when the author fixed the pydantic==2.10.6-related errors in Hugging Face and Gradio last week.
If you’re running it in a local Docker container, there shouldn’t be any changes to the training content even if you use a slightly older version, so I think it’s a good idea to try using a slightly older version. There must have been a moment when it was working.
Gradio’s behavior changes quite a bit when the minor version is slightly different, so the author doesn’t notice bugs in environments other than their own…
