I have seen that happen when a native template update did not complete.
If you build using AppCenter, this really should not happen. During AppCenter build your settings get applied. But if the config file got messed up that does not happen. Best to build the native app again from Studio Pro and check the contents of the GitHub repo.
If you build locally using the advanced flow, the template got replaced by an update but you did not build the app afterwards or that build failed. Build the app again
