Detailed steps to reproduce the problem?
While working on PYTHON-4840, I saw the following behavior on Windows:
$ pip install -e . $ python -q -X faulthandler >>> import pymongo Windows fatal exception: access violation Current thread 0x00000598 (most recent call first): File "<frozen importlib._bootstrap>", line 488 in _call_with_frames_removed File "<frozen importlib._bootstrap_external>", line 1316 in create_module File "<frozen importlib._bootstrap>", line 813 in module_from_spec File "<frozen importlib._bootstrap>", line 921 in _load_unlocked File "<frozen importlib._bootstrap>", line 1331 in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 1360 in _find_and_load File "<frozen importlib._bootstrap>", line 488 in _call_with_frames_removed File "<frozen importlib._bootstrap>", line 1415 in _handle_fromlist File "C:\cygwin\home\Administrator\mongo-python-driver\bson\__init__.py", line 147 in <module> File "<frozen importlib._bootstrap>", line 488 in _call_with_frames_removed File "<frozen importlib._bootstrap_external>", line 1022 in exec_module File "<frozen importlib._bootstrap>", line 935 in _load_unlocked File "<frozen importlib._bootstrap>", line 1331 in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 1360 in _find_and_load File "<frozen importlib._bootstrap>", line 488 in _call_with_frames_removed File "<frozen importlib._bootstrap>", line 1310 in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 1360 in _find_and_load File "C:\cygwin\home\Administrator\mongo-python-driver\pymongo\asynchronous\mongo_client.py", line 61 in <module> File "<frozen importlib._bootstrap>", line 488 in _call_with_frames_removed File "<frozen importlib._bootstrap_external>", line 1022 in exec_module File "<frozen importlib._bootstrap>", line 935 in _load_unlocked File "<frozen importlib._bootstrap>", line 1331 in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 1360 in _find_and_load File "C:\cygwin\home\Administrator\mongo-python-driver\pymongo\__init__.py", line 91 in <module> File "<frozen importlib._bootstrap>", line 488 in _call_with_frames_removed File "<frozen importlib._bootstrap_external>", line 1022 in exec_module File "<frozen importlib._bootstrap>", line 935 in _load_unlocked File "<frozen importlib._bootstrap>", line 1331 in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 1360 in _find_and_load File "<python-input-0>", line 1 in <module> File "C:\python\Python313\Lib\code.py", line 92 in runcode File "C:\python\Python313\Lib\_pyrepl\console.py", line 205 in runsource File "C:\python\Python313\Lib\code.py", line 313 in push File "C:\python\Python313\Lib\_pyrepl\simple_interact.py", line 160 in run_multiline_interactive_console File "C:\python\Python313\Lib\_pyrepl\main.py", line 59 in interactive_console File "C:\python\Python313\Lib\_pyrepl\__main__.py", line 6 in <module> File "<frozen runpy>", line 88 in _run_code File "<frozen runpy>", line 198 in _run_module_as_main Segmentation fault

Definition of done: what must be done to consider the task complete?
Diagnose the segmentation fault and support free-threaded Python on Windows.
