CI Intermittent segmentation fault in Windows arm64 wheels test (vanilla CPython)

It's been seen so far (October 13) in 2 runs over 13 runs (see [scheduled Wheels runs](https://github.com/scikit-learn/scikit-learn/actions/workflows/wheels.yml?query=event%3Aschedule)):
- Python 3.12 [build log](https://github.com/scikit-learn/scikit-learn/actions/runs/18239153780/job/51938405934)
- Python 3.14 see [build log](https://github.com/scikit-learn/scikit-learn/actions/runs/18423960080/job/52502560141) from https://github.com/scikit-learn/scikit-learn/issues/32393#issuecomment-3396312539

The information is similar in both cases seems to point the finger at
```
sklearn\tree\tests\test_monotonic_tree.py", line 511 in test_nd_tree_nodes_values
```

Relevant part of the build log:

cc @khmyznikov and @vask2108 who did the work of adding Windows arm64 wheels: https://github.com/scikit-learn/scikit-learn/pull/31867. Maybe you have seen similar things in other packages and/or you would be willing to help debug this?

COMMENT:
@vask2108 I do see the: `Access violation - code c0000005`:

[run_37.log](https://github.com/user-attachments/files/23201632/run_37.log)

To reproduce that, you need to run the test in parallel batches. I did 10 parallel 5 times, and got stable crash at run around 36-39.

This is the script I've used, place it in repo folder:
