crash when saveMesh to a byte stream on M2 MacOS (python)

[DennisEvseevMS]

The following code has regressed:

def _prepare_for_write(handle):
    handle.seek(0)
    handle.truncate()

def _prepare_for_read(handle):
    handle.flush()
    handle.seek(0)

with io.BytesIO() as f:
    mesh.export(f, file_type="ply")  # mesh is a TriMesh
    settings = mr.DecimateSettings()
    settings.maxError = max_error
    _prepare_for_read(f)
    mrmesh = mr.loadMesh(f, extension="*.ply")
    res = mr.decimateMesh(mrmesh, settings=settings)
    _prepare_for_write(f)

HERE

regression: (1) fileHandle renamed to 'out', I fixed it but (2) unhandled crash on M2

    mr.saveMesh(mrmesh, fileHandle=f, extension="*.ply")

Thanks for the report! We've fixed this in the master branch. The fix will land in the next release, which will happen in about a month.

For now I suggest either saving the mesh to a file (writing to f = open("1.ply", "wb") should still work) or installing the previous release 2.4.4.153.
