Background changes color as camera angle changes

I am having problems with which I believe, a graphics bug. I am trying to make a corridor, with 4 point lights along it. However, when I pressed play, the player’s camera starts making the environment around it change shadow for whatever reason. The screenshot is in play mode, and the other screenshot was what I expected it to look like. (The one I expected was brighter and more clear, and the reality one is darker and doesn’t blend in with the surroundings.) I feel like it’s a lighting problem, but since I am a beginner, I’m not sure what the issue is. I’d appreciate it if anyone could help me out.
