SoLoaderDSONotFoundError: couldn't find DSO to load: libreactnative.so

Description

continuation of https://github.com/facebook/react-native/issues/49111 which was closed without resolution, even though many others have the same issue.

it looks like it's only Play Store test emulators that are crashing (pixel 6/6pro/7/7a, nexus,...)
but perhaps it's also real users with real devices, not sure on that last one.

Steps to reproduce

1. run app

React Native Version

0.81.1

Affected Platforms

Runtime - Android

Screenshots and Videos

No response

Start with ReactNativeFeatureFlagsCxxInterop.kt:28 and DefaultNewArchitectureEntryPoint.kt:97, then inspect the Android native-library loading path implicated by the stack trace. Reproduce the crash on the affected Play Store test emulator if possible; done means the app starts without SoLoaderDSONotFoundError for libreactnative.so.
