`Stop Code Run` not working

If I press Ctrl+Alt+M while code is running, nothing happens. Attempting to run the command by pressing F1 and selecting `Stop Code Run` also doesn't work, and results in the following error:

`command 'code-runner.stop' not found`

I've tried uninstalling and reinstalling the Code Runner extension, as well as disabling then re-enabling it, but the command still doesn't work. I've been testing the command using a simple infinite loop written in Python, so I know that it should be having some effect when I call it.

Is there anything else I can do to get it working? If not, could someone please fix the problem?
