Can't crack the code to not get the gray screen after recording music.

I record music videos on my MacBook Pro using PhotoBooth. It's simple to use, but can't isolate what is causing the gray screens of death after I try to record some projects. I run audio through a Focusrite interface and have tried playing with the gains up and down. I've broken out pieces of songs to see if I could isolate an overload of some kind, but haven't found any way to knowingly trigger the breakdown. Very frustrating, especially after nailing a song, only to have it not be recorded.

This is the gray screen of death. Thoughts?
