Need help with this screen issue

Update: all this issue appeared after I tried some tweaks, it's no issues from Xiaomi's side

So I'm using the redmi 12 5g and this phone has been a killer in any aspect regarding to experience and performance. A week ago I got the HyperOS 2 and it was too good and now I don't know what has happend but the phone has become too laggy... Animations are not smooth and take many repetitions to get smooth.

And the worst part is that my phone is in warranty and has started a new touch issue... Basically it doesn't detect touch in all areas of the screen and the fun part is that if I double tap my fingerprint sensor and open the control panel, then there it detects all touches but as soon as I put the control panel off, it again doesn't detect touch.

Moreover I think this is a software optimisation issue and what to do now? I can't factory reset my phone.
