2d godot 3.4 game On win export After main scene screen goes gray

Hi I am having a problem with 2d win export on 3.4 godot.

I have run game in fullscreen mode and windowed mode.

It shows splash screen. then main menu. then level select then it goes to a gray screen.

In the editor the game runs fine. In 2d editor the scene seems normal and inside the blue square for camera view.

EDIT: it is not exporting all the resources in the export. I will have to discover why.

Fixed it.

There was a case conflict between resource names and variable calling it.
