Vertical pink line appears on iPhone 14 Pro Max after iOS 26 update

After a year of purchasing a 14 Pro Max, I noticed display fluctuations. Even though it was barely noticeable, the screen sometimes fades into a light green colour (mostly noticeable on a Black background). But now it crossed the limits, after the updation to iOS 26. My phone turned up a single pink vertical line on most left side of the iPhone. FYI: I don’t run any high-end games/rendering on phone, just normal usage. And I tried all solutions to remove it but it didn’t work.
