Why does my iPhone 11 make clicking static sounds when I screen record

I’ve had my iphone 11 for 3 months and about a month ago i realize when is screen record things there’s a clicking or tapping sound in the background like static or bubble wrap pops. But it only happens sometimes and only with screen recordings. Sometimes I have screen recordings that sound perfectly fine. Does anyone know why this is happening or how I could fix it?

I don’t know if you can see the videos or not but the first one is normal sound and the second is the clicking static.
