pluginWin.mel line 290: initializePlugin function failed (mtoa) maya 2018.6

[smackula]

I seem to have lost the ability to load Arnold recently, tried all the fixes in the searches i could find. not sure what happened to break it.(windows update, malware scanner etc?) maya 2018.6 and i have whatever the Arnold files i can access with the indie license subscription, tried the 4.1,4.0 installs. any other fixes or ideas? trying to avoid a clean maya re-install. any help appreciated.

1.tried uninstalling and reinstalling different versions. and reinstalling in different locations (C,D), deleting all related files i could find
2.deleted the pymel.log everytime.
3.looks like all the right files are running in the process monitor linked in other fix suggestions. all the Arnold plugins say "success"
4. maya env file is empty and not referencing other locations.

this is what the maya script editor returns when trying to load it from the plugins menu

PluginManager;

evalDeferred "shaderBallRendererMenuUpdate";

import arnold

// Successfully imported python module 'arnold' //

import mtoa

// Successfully imported python module 'mtoa' //

import mtoa.cmds.registerArnoldRenderer;mtoa.cmds.registerArnoldRenderer.registerArnoldRenderer()

# Error: file: D:/Program Files/Autodesk/Maya2018/scripts/others/pluginWin.mel line 290: ImportError: file C:\Program Files\Autodesk\Arnold\maya2018\scripts\mtoa\ui\qt\tests\test_treeview.py line 7: No module named Qt #

This is the problem:

No module named Qt # 

Run this Python in Maya. What does it print out ?

import qt.Qt
print qt.Qt.__file__
import qt
print qt.__file__
