How do I prevent the background block that has both the tool pallet and transform controls from appearing when I open a file? Ps 27.3.1

I don’t know what the thing is called. I want a floating tool pallet and whatever the strip along the top is called. I have the same issue with InDesign. When I switched to this latest version I followed the instructions for importing my preferences, but only the pallet locations and my actions transferred. Everything else reverted to the current Adobe defaults.
