my display is not responding to touch

I recently reset my iPhone 15 plus where it was on ios18, next day the phone stopped responding to the touch and unable to do anything it was fine when I was using it earlier that morning, I just kept it to charge and after it is charged I removed the cable and try to use the phone the touch doesn't respond I tried every method to fix the issue but it didn't work and I ended up resetting my phone and now the screen doesn't work and have no access to my contacts and cannot use my phone.
