iphone 12 making crackling noises when i open my camera

i’m not sure how to fix it because my camera does have a crack in it and it makes the camera blurry but i’ve been using 0.5 for the past 5 months and nothing has happened until now and im not sure what to do, it continues to make this sound even during live photos, if you click on the live photo you will hear the sound and it’s very annoying, so if anyone has any suggestions i’d be very grateful! 😊
