Messed up all the menus when creating an object

I am really new.

So I created a sculpt using Blender Render and I have actually messed up every single menu along the way somehow.
I can’t even switch from Object to Edit mode or anything. I am not done with this project.
I can reset to factory settings to make something new but I want to be able to keep MY project and reset all of the UI at teheh same time.

How do I do this? This is the first thing I have sculpted that actually looks like something, I don’t want to start over.

Please help.

Could load a new file (ctrl+N), then file menu -> open and uncheck ‘load UI’ from the dialog before opening the working file.

Local viewmode toggle is numpad_/ and it says “(local)” in the top left corner of the 3D view when active.
