jl.PythonCall.JlWrap.Cjl._pyjlbase_name crash in Python 3.13

[dpinol]

Affects: JuliaCall

Describe the bug
Just accessing juliacall.Main.PythonCall.JlWrap.Cjl._pyjlbase_name crashes python 3.13.3. It doesn't crash python 3.12.
I know it's a private field, but what I actually wanted to do was juliacall.Base.summarysize(juliacall.PythonCall) which crashes due to _pyjlbase_name

from juliacall import Main as jl

jl.PythonCall.JlWrap.Cjl._pyjlbase_name

I tried to patch it with jl.Base.setglobal_b(jl.PythonCall.JlWrap.Cjl, jl.Symbol("_pyjlbase_name"), "juliacall.ValueBase"), but I get "invalid redefinition of constant Cjl._pyjlbase_name".
