RuntimeError (watchdog ): dictionary changed size during iteration

Using Streamlit
1

Hi, I have recently upgraded from version 1.44.0 to 1.46.0.

When I run my Streamlit app locally, I encounter the following RuntimeError in the terminal, although the app is not crashing. ChatGPT suggests:

“The error originates from the watchdog package, which is commonly used for monitoring file system events. The dispatch_events method calls a handler that processes events, and it seems this handler is trying to modify a dictionary while iterating over it.”

What should I do about this? Is it a bug in the new update?
