Camera error in iPhone 16 Pro Max while scanning QR code

IP16 Promax Error Camera.

I'm using iPhone 16Promax, with iOS 26.2.1 , MYX33VN/A model

Currently, I often have camera errors when starting up and cannot use QR code scanning for payments when scanning QR codes. This phenomenon happens when I start updating to iOS 26. I have also updated version 26.2 but it's still at work, I have to restart to open it. Please guide me to fix the error
