Running on mac OS Sonoma, with jpterm version… either 2.3 or 0.2.11? I’m not sure how to read the version information from pip and the program doesn't come support for a --version command line flag.
(Output from pip inspect)
// [...]
{
"metadata": {
"metadata_version": "2.3",
"name": "jpterm",
"version": "0.2.11",
"summary": "Jupyter in the terminal",
// [...]
}
I can get as far as this menu:

Trying to select anything in that Select dropdown by pressing Enter puts the program into this state:

Quitting with Ctrl-C just yields a message about handling the KeyboardInterrupt, which is of no diagnostic value.
^C^CException ignored in: <module 'threading' from '/opt/homebrew/Cellar/python@3.11/3.11.5/Frameworks/Python.framework/Versions/3.11/lib/python3.11/threading.py'>
