iPhone Stuck on White Screen

My iPhone 13 Pro Max was experiencing issues where the display was flashing. After updating it to iOS 26, which was what I was instructed to do, the screen turned white completely, although the screen was responding to my touch. I force restarted it, which didn't work after multiple attempts. While it was in recovery mode, I updated it by connecting it to a Mac, which didn't work as well. I then tried restoring it, which worked, but the screen turned white once I finished setting it up. Is this a problem regarding the iOS 26 software update? Are there any possible ways I can fix this at home?

Thanks in advance to the Apple Expert who answers my question.
