iOS build crashing on splash screen

I’m trying to build a very small game (only two scenes) and up until today, I was having no problems but now it constantly crashes when I build to my iPhone 5s. It’s weird because if it crashes the first time, it’ll always crash, but if I get a build working that doesn’t crash, it never crashes. It also flashes red for some reason too.

I’m not super knowledgeable about working with hardware, so I don’t have much idea as to why a game would be crashing on the splash screen, before it even loads the main menu. Any insight on to what I should check? It seems to only do this when I try setting up a custom splash screen using the Project Setting->Player Splash Screen tool, so I thought maybe the logo image was too large, but that doesn’t seem to matter. However not doing any custom splash screen seems to work fine.

I also don’t know how to set up the Xcode crash reporter so I’m trying to learn how to do that.

Does this happen when running via Xcode? If so then what is Xcode telling you?
