I'm going to need more information to help you.
What version of Windows do you have?
When starting the game, do you see the game window appear and then disappear, or does it not show up at all?
I have had the same issue. While it's not a permanent fix, you can get around it by clicking and holding onto the top bar while it loads. The tako will load in and stay on screen after you let go.
And make sure you right-click to move it before anything else, or it may disappear when you scroll or click off
