Bottom right of my phone won't detect touch after update

My oppo reno 11 got the latest update today and the bottom right corner of my screen at the edge wont detect any sort of touch, any time i try to press or click something on that spot it just doesnt register so nothing happens. i've already restarted my phone but its still the same. my phone was perfectly fine before this update that happened today. does anyone know what to do :(
