The file has a number of User Actors, from your description I am not sure which one is the root of the failure.
DX - PY - Browse for File (win+mac) :
does this user actor allow you to select a file on your hardrive?does the filepath get inserted to the next user actors 'cube_path' input?
DX - PY - Load .Cube for Color Grading :
does the 'status' output change if you click the 'load' input triggerif you open this user actor to look inside, do you see a red Hazard symbol on the Pythoner actor?is the status output = "status: ❌ LUT file not found"
I suspect you will see the red hazard on the pythoner actor once you look inside the "status: ❌ LUT file not found" actor.
Like this:
If you do, then the Python environment is not setup correctly. Scene one requires Numpy be installed, and scene 2 requires Numpy and OpenCV.
If you go to Help/Open Plugin folder in the menu, and read the last line on that menu you should see 'Python Virtual Environment' ...
What does the rest of that line say?
note: The asci error might have been due to unexpected characters in a file name/path.
