Support for cython speedups using PyDev in Eclipse with Python 3.12

Question

I'm using a fresh install of the latest Eclipse, PyDev and Python 3.12. I get a warning warning: Debugger speedups using cython not found when debugging some Python code. (I've run the suggested command for setup_pydevd_cython.py but the warning persists.)

I traced the warning to the end of pydevd_frame_eval_main.py with the call to pydev_log.show_compile_cython_command_line(). I modified the file to print the ImportError and got the message:

Traceback (most recent call last):
  File "C:\Users\Alex\.p2\pool\plugins\org.python.pydev.core_11.0.3.202310301107\pysrc\_pydevd_frame_eval\pydevd_frame_eval_cython_wrapper.py", line 3, in <module>
    from _pydevd_frame_eval_ext import pydevd_frame_evaluator as mod
ModuleNotFoundError: No module named '_pydevd_frame_eval_ext'

During handling of the above exception, another exception occurred:

I noticed no _pydevd_frame_eval_ext folder exists in the pysrc path. Also, the _pydevd_frame_eval folder has no .pyd file for Python 3.12 (it stops at 3.10).

How can I get cython speedups to work for my setup?
