Sketching plane used for Sketch2D was deleted (Molded Forms)

Meaning: Failed to retrieve the sketching plane. The sketching plane has been modified or deleted.

Recovery: Select the object in the To Do List. For some objects, such as a sketched profile, you cannot select a new plane on the ribbon bar. An alternative is to use Tools > Change Geometry Type to change the profile to a different profile type. After you change the type, you can change the type back to profile by projection if needed.

You might need to modify the 2D sketch in some cases. For example, the new plane might not be parallel or coincident with the previous plane.
