All cameras on my XS Max get blurry

So, yesterday FaceID suddenly quit working and I tried resetting it. Still wouldn’t work and after a closer look, I noticed a few air bubbles (I think that’s what those are) inside my front-facing camera. A few hours later, it filled the entire camera and it was all blurry when I wanted to take a picture. I woke up this morning to find that a quarter of it has gone, but the rest is still there, making my front facing camera barely usable. Does anyone have an explanation for this? I also have this problem with my rear cameras though I made another post for that. I didn’t drop my phone nor did it encounter water damage.
