iOS 18.2.1: Apps Refreshing When Returning from Background

I am using an iPhone 14 Pro Max, and I’ve encountered an issue that started when I updated to the public beta of iOS 18.2. Here’s the problem:

Whenever I minimize an app (e.g., WhatsApp, Safari, Chrome, Brave, etc.) while working on something—like typing a message or filling out a form—and receive a call, the app refreshes to its initial state after I return. For example:

If I’m typing a message in WhatsApp, and a call interrupts me, the chat window closes and reverts to WhatsApp’s home screen when I return. Similarly, if I’m filling out a form in a browser and get a call, the form resets, and I lose all entered data. If I’m playing a game like Candy Crush and switch to another app without closing the game, it restarts when I return. If I’m trying to log in to an app that requires authentication through another app (e.g., SEB Bank app using BankID, or Swiss apps that require BankID for verification), the login process fails because the original app refreshes and loses its state when I switch back. Initially, I thought this might be due to having Developer Mode enabled, so I turned it off. Then I assumed it could be related to the beta version of iOS, so I waited for the stable release. I have since turned off beta updates and updated to the stable version of iOS, but the issue persists.

Interestingly, I noticed the same behavior while using iOS 17 as well.

Is there anything I can do to fix this problem and prevent apps from refreshing unexpectedly? Any help or insights would be greatly appreciated.
