    How do I solve this PARM error in Illustrator?

    This is the error I am getting after performing an image trace.

    "The operation cannot complete because of an unknown error. [PARM]"

    I converted some older documents of mine to cloud documents recently, and keep running into this error almost nonstop when trying to work on them. I was just working in a cloud document that was brand new without issue, but when I tried another document I converted to the cloud format I ran into the same issue.

    MAC Pro MAC OS 10.14.6 Illustrator 25.4.1

    The error message in the subject comes when I undo an action. For example, I move an object and then I go to edit, undo move, and then the error message comes up. If I then press ok, I can undo the action.
    The last 3 updates did not help.

    Adobe Illustraor CC 23.0.1

    Constantly getting this error message:
    The operation cannot be completed because of an unknown error [PARM]

    Click 'OK' and get error message:
    An error occurred while processing the appearance of an object

    Occurs randomly when drawing shapes using pen or shape tool, with or without fills. Last occurrence was when using knife tool to intersect a shape.

    If I click 'OK' error re-occurs immediately.

    Happy to have any ideas?
