    Description

      Creating a CMake project with 2 modules (lets say main module as UI and second as backend will fail on Android second run if the build directory is not cleaned.
      Cleaning the build directory will run application correctly on device.
      Adding manual STATIC to qt6_add_qml_module is fixing the issue, but letting it empty or setting it SHARED is confirming the issue.
      I tested on the latest QtCreaor available on mac and window with NDK 23 and 25

      Attached is a working code which can be opened on QtCreator.
      Open it, run.
      Will run the app (just a blank window)
      Run it again (build and run to be specified) and the following error is raised:
