Get out of Artboard mode

[hcbphoto]

Hello,

I seemd to have put myself in Artboard mode and I can't get out of it.  I was working earlier in my normal manner having my Move tool as the first icon.

 I finished my work and shut down. Later, I had to work on something else.  I went ahead and crated a new document.  
I no longer can duplicate a layer, add another photo, etc.  Basically, all functionality that I was able to do before I no longer am able.

I noticed that my Move tool has disappeared and is replaced with an Artboard tool.  When I go to Window and select history, it clearly says Artboard.

I have no idea what I did.  I thought I exited Photoshop as I normally do. Apparently not.

 I don't want this Artboard. I want to return to my previous workflow. 
How do I get out of this mode? I have clicked and double-clicked in various areas based on feedback from other posts. I am not finding anything to resolve this.

Can someone please help me?
Thank you in advance.

Hi,

I saw this post. I'm using the latest version of Photoshop.  I believe it's CC 2021.  The post has screen prints from 2015.

As far as "selecting all my layers", I have no layers except for the background layer.  I can't unlock it, I can't duplicate it, when I right-click, I do not receive the same options.  
Unfortunately, the post isn't helpful.

What about a screen shot?

What does <shift>v do?

I have the Artboard tool coupled with the move tool:

or may be this helps:

I really would like it go away completely, if possible.  
I have no knowledge of the Artboard. This is the first time I'm hearing of it.  
There's a way to get into it.  There must be a way to get out.

Any idea on how I even managed to get the Artboard?
