Weird Screen when launching game for windows

I'm developing an application for android and windows, and the trouble I'm having is that the application works on android, and also works in windows but only in the editor. I can launch the app just fine in the editor and play through everything, but when I build and launch as a separate exe I don't even get the unity logo screen and instead get this:

it is fullscreen and sometimes just a black or white screen. When I built the game the first time and ran it as an exe it worked fine, until I reached a point where I knew it would crash because I'm modifying the code still to work with both android and windows, it was supposed to play a video, and instead I got the screen above.

Now whenever I launch the exe again I get this screen, and it doesn't matter if I rebuild the application or delete the data and rebuild, even unselecting every scene and building gives me the above screen now! If any one has an idea what this I'd be much appreciated, as it stands, I don't even know where to start to debug this since in the editor the app works as intended.
