import ifcopenshell failed with error "signed with custom identity or adhoc?" on the macOS M1

Hello, team.

Does anyone know how to fix the error "signed with custom identity or ad-hoc?"
When I execute import ifcopenshell in the FreeCAD App, I got the following errors.

Best regards.

>>> import ifcopenshell

I succeed in loading iopenshell in the python 3.10.

This looks like a macos-specific error... Googling for "mapped file has no Team ID and is not a platform binary" returns some results, but it's not clear to me what the problem is... Any idea @chennes ? Could it be that our signed FreeCAD now prevents importing unsigned python modules?
