iPhone 16 Camera Not Working on WhatsApp—Error Won’t Go Away

I keep getting a "Camera could not be started" error every time I try to use my iPhone 16’s camera on WhatsApp. I have restarted the phone multiple times, updated the app and iOS, yet the issue still persists.

Even when I open the default camera app, it either takes too long to load or fails to open entirely, making it impossible to use. I have been dealing with this issue since I bought the phone, and I am tired of it.

Apple needs to fix this problem immediately, or I expect a refund so I can upgrade to a higher model (such as the iPhone 16 Plus, if this issue is not a known defect in that version). I need a resolution now!
