Python 3.13 with no gil - SystemError: init function of orjson returned uninitialized object

[prabhu]

I am getting this error, while testing my project with python 3.13 with free-threading. Used the below code snippet to setup this in GitHub actions.

- name: Set up Python
       uses: deadsnakes/action@v3.2.0
       with:
         python-version: '3.13'
         nogil: true

Copy the actual failure here? That link doesn’t show any details under my account.
