When doing Override of a vanilla prefab, generating an Editable file from it creates an invalid editable (E_) file. This file cannot be edited, and it eventually makes WorkBench crash. See the attached .mp4 video showing this.

Instead of crashing, a dialog box should pop up and say the editable prefab already inherits the changes from the selected prefab Override.

Or instruct the user to override the vanilla E_ prefab file (if this won't cause issues).
