- the Artboard name does not appear on the editing space.
- Ctrl + Z does not work to revert the changes after pasting the borken artboard to somewhere else.
2. When copying the existing component into a new XD file to save it, an error message appears with unknown code. It end up with creating another broken XD file.

Background info
We are currently not using Adobe Creative Cloud as saving space; we are instead using Google File Stream, and we use versioning feature of it. Therefore, from XD perspective, it is saving local drive.
Note
We first thought "Components within another Compont" may have potential bug in current version, and it would be one of the causes; however, we could not completely understand the cause of this broken XD file.
