iPhone 16 Pro Max QR scanner goes black in PhonePe, Google Pay, Paytm, and native app after updating to iOS 18.5

I’m using an iPhone 16 Pro Max and have updated to the latest iOS version (18.5). However, I’m still facing an issue where the QR scanner goes black in apps like PhonePe, Google Pay, Paytm, etc. The only temporary fix is restarting the phone, which is inconvenient and frustrating, especially when I need to make quick payments. Please look into this and provide a resolution as soon as possible. It’s causing a lot of discomfort in daily usage.
