OK, you get
ImportError: cannot import name 'unicode_to_str' from 'IPython.utils.py3compat' (/usr/lib/python3.13/site-packages/IPython/utils/py3compat.py)

which should be fixed by
the PR 41141.
(github.com/sagemath/sage/pull/41141)

Not sure which version of Sage you talk about, but this should be applicable to the latest beta.
(not yet merged though)
