Little snippet to remove "CgAbBlastPanelOptChangeCallback" error from Maya scene - // Error: line 1: Cannot find procedure "CgAbBlastPanelOptChangeCallback". //

maya_remove_CgAbBlastPanelOptChangeCallback.py

"""
This will iterate all modelPanels and remove the "CgAbBlastPanelOptChangeCallback"

As such, after running this the following error should be fixed:
    // Error: line 1: Cannot find procedure "CgAbBlastPanelOptChangeCallback". //
"""

from maya import cmds

for model_panel in cmds.getPanel(typ="modelPanel"):
    
    # Get callback of the model editor
    callback = cmds.modelEditor(model_panel, query=True, editorChanged=True)
    
    # If the callback is the erroneous `CgAbBlastPanelOptChangeCallback`
    if callback == "CgAbBlastPanelOptChangeCallback":
        
        # Remove the callbacks from the editor
        cmds.modelEditor(model_panel, edit=True, editorChanged="")

Thanks @BigRoy I will see if this solution solves this problem
