Render Settings - access to the common tab Arnold

[Anonymous]

Hello everyone, I need help
I can no longer access to the Arnold common tab because it is too small
I saw on other requests of this type, a person deleted the objects on scene and the tab became normal
But it didn't work for me

and no problem for the others tab

(I use Maya 2020)
someone can help me ?

Deleting the prefs would be my first try.

The problem is related to the scene, I tested it anyway but that doesn't change.
When I open any other scene there's no this problem.
but thanks for trying to help

I find this error:
1)
# Error: line 1: UnicodeEncodeError: file C:\Program Files\Autodesk\Arnold\maya2020\scripts\mtoa\ui\globals\common.py line 923: 'ascii' codec can't encode character u'\xe9' in position 3: ordinal not in range(128) #
2)
# Error: file: C:/Program Files/Autodesk/Maya2020/scripts/others/unifiedRenderGlobalsWindow.mel line 1774: RuntimeError: file C:\Program Files\Autodesk\Arnold\maya2020\scripts\mtoa\cmds\rendererCallbacks.py line 648: Error occurred during execution of MEL script

And this line code to the location but no idea about the problem:

1)
line 923:
# List all mono perspective cameras first
for camera in monoCams:
if cmds.getAttr('{}.renderable'.format(camera)):
renderableCameras.append((camera, False))
else:
nonRenderableCameras.append((camera, False))

2)
line 1774:
else
{
callbacks -executeCallbacks -hook "rendererAddOneTabToGlobalsWindowCreateProc" $createProc;
}

line 648:
if createProc in createProcs:
mel.eval(createProc)

but not sure this lines code is the problem
