[2023] how do you switch from cadet HOI4 to Vanilla HOI4

Eruth said: What is Cadet Hoi4?

There used to be three different editions of HoI 4: Cadet (the base game), Colonel (with additional 3d Tank and Cruiser models included) and the Field Marshal edition (containing also the first two expansions). However both the Colonel and the Field Marshal have been retired long ago.
