Hello,

the exact same error occurs for me:

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!
