Hello,

the exact same error occurs for me:
https://emacs.stackexchange.com/questions/72243/macos-org-babel-python-with-session-output-give-python-el-eval

I use python 3.9 so guessing switching the version won't help.

#+begin_src python :session :results output

print("yes")

#+End_src

#+Results:
: __PYTHON_EL_eval("try:\n    with
open('/var/folders/16/snlwm5z17zz1b1x09vvvrdg04v6pgk/T/babel-hWQZ8X/python-sPLVoL')
as __org_babel_python_tmpfile:\n
 exec(compile(__org_babel_python_tmpfile.read(), __
org_babel_python_tmpfile.name, 'exec'))\nexcept:\n    raise\nfinally:\n
 print('


do you possibly have any idea on how to fix this?

Sorry to bother you and thanks for the attention!
