<https://developer.android.com/reference/android/app/Activity.html>

The documentation literally tells you:

onBackPressed()
This method was deprecated in API level 33. Use OnBackInvokedCallback or
androidx.activity.OnBackPressedCallback to handle back navigation instead.

Starting from Android 13 (API level 33), back event handling is moving
to an ahead-of-time model and Activity#onBackPressed() and
KeyEvent#KEYCODE_BACK should not be used to handle back events (back
gesture or back button click). Instead, an OnBackInvokedCallback should
be registered using Activity#getOnBackInvokedDispatcher()
.registerOnBackInvokedCallback(priority, callback).
