[Solved] C2 loading bar turns red, load freezes

You see the C2 gear logo, the loading bar is blue until about 64% and then it turns red and everything freezes. What is happening and how do I debug this?

I started the app in regular mode (not debug) then hit F12 to bring up console. For some unknown reason it was not finding the tilemap .png file. Looked in the project and it the tilemap had no image. Had to reload the tiles .png. No clue why this happened
