Emacs 28.1: error when running Python

[gougouzhang]

I shifted emacs 27.2 to emacs 28.1, but met the error "Process Python exited abnormally with code 49" when I pressed C-c C-p to call an interpreter, which goes well with emacs 27.2 plus Prelude.

What's the error message that you get from the subprocess itself?
