Resolution Note (2018.3.X):
This behavior occurs because the TMP Essential Resources have not been imported into the local project.
These resources must be imported in the local / user project prior on first use / creation of any TextMesh Pro components.
As seen in the video when the TextMesh Pro component is first added, a window / dialogue shows up informing the user the TMP Essential Resources need to be imported. Failure to do so will result in errors.
These errors can easily be avoided by simply importing the TMP Essential Resources.
