How to fix vertical green line and glitch on iPhone 15 Plus screen after updating to iOS 18.3.2?

I am facing screen display issue after update ios 18.3.1 to 18.3.2 and The vertical green line can be seen on the display And Glitch. Please help in this regard. Hard reset is not helping either. What is the use of buying such an expensive phone when we have to face all these problems. The phone runs well on the stable version but whenever you update it, some problem or the other keeps coming up in the phone
