Run streamlit cache clear

You will get output similar to this which will tell you where is your .streamlit directory exactly, take this path before the cache part.

Nothing to clear at {Username}{path}.streamlit\cache.

cd {Username}\{path}\.streamlit

You’ll be able to see config.toml here just delete that file.
