Game Won't Fully Load- wont go full screen, minimized- "Not Responding"

[EnderzShadow.2506]

In the last week, the game won't fully load.

 

While I am loading in, it will flash between the desktop and the game (back and forth). It has done this since I've had this pc.

But this last week, it stays alt tabbed, not responding, on my desktop while showing the in game cursor. It's like it gets confused.

 

Everything has been kept updated.

Any idea whats going on?
