Resolution Note (fix version 1.5.0-preview.12, 2.1.0-preview.12, 3.0.0-preview.12):
setting the atlas texture of a text object to None or Null will result in the text rendering as white blocks. Although the NullReferenceException will no longer occur, it is not advisable to set the atlas texture of a text object to None / Null.
The fix for the behavior will be included in the next release of the TMP package which is expected to be Preview 12.
