Hi, I have a problem trying to Run my current APP.

I have two functions:
Window::load();
Window::start();

I want to move some images using the start() method, but there was some issue the way I added the images to the Scene so I change the code in the load() method.
Once I changed the way I added the images, I have to change the whole code of movement in the start() method for sure. But I can't even erase everything in this method and create new statements cause every time I try this, this error shows up:
... Execuatable "PATH_HERE.exe" does not exist.

I tried to delete this method, and create a new one, but the same code still appear.
I set the whole code as a comment block(the old code of the start() method), and tried to start writing the new code, but the same error keep showing up.
The only way I can make new code is, not using the start() method, but I have to create a new method and make my new code.

What can I do? how to delete this function that is causing this error.
