Black screen when running. NO errors?

There is a black screen when running my project. I can hear the music and click buttons, but I can't see anything. There are no errors and I have no idea what to do. It works in an empty project so I assume there is a problem with my elements. I even removed some finicky entities and it is still black. Neoforge 1.21.8

Any help is VERY appreciated. (ai made it worse)
