Clone of a working scen is BLACK on BUILD

This scene is a clone of another one. and has MINIMAL changes. a few extra enemies. doesn’t interact with camera at all. my other 6 scenes work but this one doesn’t. i don’t even know where to begin because this is a clone of a working scene that works perfectly on build.

Mind you this scene works perfect in editor. any ideas?
At one point the UI for this specific was working but the rest of the level is all black.

i read online how antialiases can cause this but this didn’t do the trick for me. any ideas?

I’m getting somewhere. so apparent if i move the camera down the hierarchy, it starts to kinda fix it itself. i no longer have a black screen but there’s no sound and rarely any color. This has to be a bug of some sort…

Also, my main camera isn’t parented to anything so why does the hierarchy matter?
