- Download and Install all available updates. Restart when required.
- After restart check for updates again to make sure all updates have been installed

Hi Giby,

I faced the same issue for many times, then I found out that one way or another, some of Mendix Native file got deleted and there were some missing files, you can try to delete the marketplace modules you are using  for Native such ass NanoflowCommons, NativeMobileResources or anything related to it then re-download it again

 

Hope this will work
