[Python] How to quietly exit a runfile script?

I am using Spyder 6 console to invoke a Python script via the runfile command. After a recent Anaconda update, I found that sys.exit() no longer exits the script quietly. It prints:

An exception has occurred, use %tb to see the full traceback.

SystemExit: 0

C:\Users\User.Name\AppData\Local\anaconda3\envs\py39\lib\site-packages\IPython\core\interactiveshell.py:3534: UserWarning: To exit: use 'exit', 'quit', or Ctrl-D.
warn("To exit: use 'exit', 'quit', or Ctrl-D.", stacklevel=1)


Using exit() and quit() are equally verbose.

I came across suggestions to use sys.exit(0), but it doesn't change anything for me. I want to avoid os._exit() because it skips cleanup handlers.

How would I gracefully and quietly exit a script that is called with runfile?
