Offline packages can't be added to the local file system

Hi,

I’m trying to update a project from 2023.1.16f1 to 2023.3.0a15 to test the GPU Driven rendering.

The project is on a computer that has no access to internet (this is a company policy).
I fixed the issues related to text mesh pro package merged with unity UGUI ( [2023.2] Latest Development on TextMesh Pro ).

But now I have this issue, without more details in the log file.

The packages are missing, so everthing is broken. Are those packages shipped with the editor like in final versions?

Things I already tryied:

  • Close Unity, delete Library, obj and Logs folders and reopen the project
  • Remove and re-add the packages throught the package manager window
