Error with Blendshape window

[Anonymous]

I made the huge mistake of trying to bring back the old blandshape window. I used BlendShapeEditor on the script editor and now everytime I open the file my computer freezes for a second and the Blendshape window pops up and I get this error

// Error: "C:/Program Files/Autodesk/Maya2018/scripts/others/createBlendShapePanelMenu.mel" line 145.18: "$cmd" is an undeclared variable. // 

Please help is really annoying

did you solve this problem? I have the same issue.

Yes, there’s a option on the open box where you can disable the extra windows.
