Please help me!!

I own an iPhone 15. I’ve been having this issue recently where for some reason I can’t type the letter t.

When I press it, it just switches to R or Y and some times it’s T. I usually just use AutoCorrect like I’m using right now, but I can’t do digital art too cause I’m a digital artist so when I use my fingers this swipe, it’ll just glitch and won’t even let me draw. Please any advice I’ve also upgraded to the iOS 26. I removed my phone screen protected and cleaned my phone and it still didn’t work!! Please I’m so stuck!!
