    Horizon returns an error when admin edit CPU Assignments

    The error occurs due to a bad reference of utils module, which is being
    loaded from another path, instead of being imported from the directory
    where the utils module is located.

    Updated the path reference to load utils module properly.

    Closes-Bug: 1993662

    Test Plan:
    - Edit CPU assignments on the controller that is locked.
