The key error message is:

   ** Severe  ** IP: IDF line~562 Object=CONSTRUCTION, name=E, Required Field=[Outside Layer] was blank.

This is saying that you have a Construction object in your model, where the Name input field is set to E. The next input field for Outside Layer was left blank. The Construction object is ultimately a simple list of names of Material objects in the same IDF ordered from outside material layer to inside material layer. If you leave these input fields blank, then your construction assembly has no layers.

If you search for the object causing the severe error in a text editor, it will look something like this:

Construction,
  E,                  !- Name
  ;                   !- Outside Layer

If you search for the object causing the severe error in IDF editor, it will look something like this:
