Segfault on M3 when loading specific Python subpackage

Affects: PythonCall

Describe the bug

On a M3 Mac I can produce a segfault when loading a specific subpackage, simpeg.potential_fields from version 0.22.0 of the simpeg package (https://github.com/simpeg/simpeg). When I import just 'simpeg', there is no segfault. Furthermore, other subpackages do not produce segfaults when loaded, e.g., simpeg.maps.

Here are the commands used to reproduce the segfault. (The output of some steps has been shortened; I will include a full output in a reply.)

Additional context

Running Python (from .CondaPkg/env) and importing simpeg.potential_fields directly does not cause a segfault, see example below.
This segfault does not occur with simpeg version 0.21, and the version 0.21->0.22 changed the package name from SimPEG to simpeg.
This bug is similar to issue #315, except this bug is specific to a subpackage
