Streamlit Cloud stuck on Python 3.13 ignoring config.toml (request runtime rebuild)

Using Streamlit

Hi Streamlit team,

My app on Streamlit Cloud is stuck using Python 3.13.9 even though I have
a .streamlit/config.toml specifying:

[server]
pythonVersion = “3.11”

Build logs consistently show:
“Using Python 3.13.9 environment”

I have rebooted the app multiple times, but the runtime does not rebuild.
It seems the environment is cached at the app-slug level.

Could you please help clear/reset the runtime environment for this app
or force a rebuild with Python 3.11?

App name: personal-cashflow, personal-cash-flow
Repo: GitHub - ZyroFrost/personal_cashflow: A personal finance tracker built with Python and MongoDB.

Thank you.

There is no pythonVersionconfiguration option in [server]. The runtime and Python version must be configured before the Streamlit server starts (at which point config.toml is used).

To configure the Python version of your app on Community Cloud, you need to edit your app settings:
