Can't swipe left to go back anymore on iPhone X IOS 14

Hello,

So basically I've recently tried the beta of IOS14, not sure which beta it was but I'd guess it was first the beta 5 and then I updated it to the following ones, and now, since the official one was released, I'm currently operating on IOS14.0.

The problem started some betas ago and thought that it'd just be a firmware bug, since it was still a beta. But I still can't perform the "swipe left" to go back in the various apps, for exemple in Whatsapp to exit a chat (not only the apps, but the iPhone settings as well) and this is getting on my nerves, since I've bought an iPhone especially for the gestures it's got. I have to specify that the touch screen works properly, it seems like it's not calibrated. Similar thing happens when I try to press the "1" key on the keyboard and it types "2" instead, it only works if I really precisely type 1 on the top left of the screen.

Moreover, I've tried multiple times to swipe from the left in various circumstances (for example in the home screen) and it responds pretty well anywhere I try to do it, so I'd suppose it's a software-related problem rather than hardware but still not sure if it's related to the IOS14 because no one else has had the same problem as me. I've also restored the entire phone, problem persists.

Any suggestions?

Thank you all in advance!
