Ear speaker stopped working after iOS 18.5 update on iPhone 12

The earpiece speaker on my IPhone 12 stopped working after I recently updated my phone to the new IOS 18.5 There have been not settings changes, no physical damage and YES, I’ve already tried every single ‘fixing sound issues’ article on Apple Support along with YouTube. None of those things worked. Please Apple resolve my issue.
