App switcher lag problem

I have an iPhone 12 Pro Max and everything works perfectly except, very often, when I swipe up to go to Home Screen from any app, there’s a slight lag. This did not happen earlier but it’s happening very frequently now. I have rebooted multiple times and have updated to the latest version of iOS. Does anybody know what to do?
I don’t have the answer. But you’re not alone this same issue has been bugging me for the longest

Greetings  everyone

I've been enduring this so called app switcher lagging since six month's ago until today that I finally discovered that  it was I caused by some IOS third party applications that been overlooked , due to data corruption of this third party apps that will be automatically installed after factory reset by IOS and consequently being discovered  as a first party app and ignored to be re-installed  after the upgrade which it will prevent some users to reinstall them after updates including (file , notes , reminder , calendar  , contacts , voice memos ,weather ,maps, calculator applications ) and  utility applications (compass , measuring ) which they are made by apple . as a result  in order to remove the corrupted information of this applications they  must be reinstalled including any other third party applications that where installed in you 'r phone before the upgrade  . However the second solving that I discovered is turning off the perspective zoom of wallpaper which can be turned off from : settings > wallpaper > choose a new wallpaper > after choosing your wallpaper turn the perspective zoom off. At last I'm demanding everyone to please do these  steps  and share your ideas with me.
