Phenomenon of returning to initial screen after external link

When clicking an external link within the webview, it is set to open in an external browser. After clicking and returning to the app, the webview automatically changes to the initial screen. This behavior didn't occur originally, but it has been happening from a certain point. When proceeding in the median simulator, it works normally as before. Why does one get reset while the other doesn't? Also, how should we approach solving this problem?

My current Android version is as follows: Android v14
