Error in Arnold Script - 'None-Type' Object is not subscriptable

[zacharywise9]

Hello, I'm new to Maya and when I try to use the Arnold lighting tools such as Area Light, Photometric Light or Sky dome Light. Nothing Happens. I'm given this warning message. 

# Warning: Unrecognized node type 'aiSkyDomeLight'; preserving node information during this session.
# Error: TypeError: file C:\Program Files\Autodesk\Arnold\maya2023\scripts\mtoa\utils.py line 547: 'NoneType' object is not subscriptable

When I try to use light portal or physical light I'm given this message. 

import mtoa.ui.arnoldmenu as arnoldmenu; arnoldmenu.doCreatePhysicalSky()
# Error: AttributeError: file C:\Program Files\Autodesk\Arnold\maya2023\scripts\mtoa\ui\procview\ProceduralWidgets.py line 21: module 'maya.cmds' has no attribute 'arnoldPlugins'

I've tried uninstalling and reinstalling but the problem persists. 

For someone who isn't a programmer. How might I go about fixing this?

Maybe you don't have the arnold plugin loaded? 

If you go to windows>setting and preferences > plugin manager, search mtoa, and make sure it is loaded.
