BUG: ArgKmin64 on Windows with scipy 1.13rc1 or 1.14.dev times out

In MNE-Python our Windows [pip-pre job on Azure has started reliably timing out](https://dev.azure.com/mne-tools/mne-python/_build/results?buildId=29467&view=logs&jobId=dded70eb-633c-5c42-e995-a7f8d1f99d91&j=dded70eb-633c-5c42-e995-a7f8d1f99d91&t=d18f7f2f-13af-5901-1cbc-7fa039d0db3a) (and a [second example](https://dev.azure.com/mne-tools/mne-python/_build/results?buildId=29468&view=logs&j=b9064c46-2375-5b70-72c1-f55d0d61c63a&t=22e60518-c9c9-558d-d42d-7392b6cf8931)):

Our code just calls the following (and hasn't been changed):
```
    clf = LocalOutlierFactor(n_neighbors=n_neighbors, metric=metric)
    clf.fit_predict(data)
```
which eventually in the traceback points to the line:

https://github.com/scikit-learn/scikit-learn/blob/e5ce4bc0f6eb8fe21cd4e3dcebabefcc5485f907/sklearn/metrics/_pairwise_distances_reduction/_dispatcher.py#L278

18 hours ago all our tests passed [in 40 minutes](https://dev.azure.com/mne-tools/mne-python/_build/results?buildId=29454&view=logs&jobId=dded70eb-633c-5c42-e995-a7f8d1f99d91), then 3 hours ago it started [failing 38% through the tests with a 70 minute timeout](https://dev.azure.com/mne-tools/mne-python/_build/results?buildId=29460&view=logs&jobId=dded70eb-633c-5c42-e995-a7f8d1f99d91&j=dded70eb-633c-5c42-e995-a7f8d1f99d91&t=d18f7f2f-13af-5901-1cbc-7fa039d0db3a), and gets to the point only ~27 minutes into the build:

This suggests that the latest scientific-python-nightly-wheels upload of scikit-learn (and/or NumPy) 11 hours ago caused something in here to hang, so probably some recent PR to sklearn or NumPy is the culprit.

Not exactly a MWE -- I'm not on Windows at the moment but could switch at some point -- but maybe someone has an idea about why it's happening...?
