Blender Version
Broken: 3.1 - 3.4 Alpha (including LTS)

Short description of error
blender python error in Arm and Apple Silicon builds, but not Intel builds.

Exact steps for others to reproduce the error
This error was in an addon, whittled it down to this one python command.
There is another error in this addon for Apple Silicon, but have not traced it down to something simple yet. So I have to use the Intel build on my M1 build.

on Apple M1 go to python console
type in :
import bpy
bpy.ops.export_scene.obj

Throws following error on Apple Silicon builds

import bpy
bpy.ops.export_scene.obj

Traceback (most recent call last):

I personally can not reproduce the issue with the system information found below.

Maybe I'm not doing something right. Am I supposed to fill out the bpy.ops.export_scene.obj command with information like bpy.ops.export_scene.obj(filepath="/folder/file"...) or is the command given enough to cause the issue?

It's pretty well explained above:
on Apple M1 go to python console
type in :
import bpy
bpy.ops.export_scene.obj

I can get a similar trace on Windows when the .OBJ addon is disabled in user preferences (User Preferences -> Addons -> Import-Export: Wavefront OBJ format (legacy)):

Traceback (most recent call last):

That error in such a situation is expected. Can you check and see if that might be the case for you? If so, you might have to help investigate why that addon was disabled for you - it should be enabled by Default. Did you try to transfer settings from an older version or similar?

@deadpin That was it. Not sure why it was unchecked, but yes, I often transfer settings from an older version.
thanks a bunch
