D5 Model Visibility Issue

Hi D5 Team,

I need urgent help with a D5 project file.

My D5 project file size is around 4.3GB , but when I open it, I cannot see my model/project in the viewport. The screen only shows sky/empty environment.

I tried the following already:

  • Opened different saved scenes from the scene list
  • Tried to locate/focus the model
  • Checked the Object panel
  • Checked the Imported panel
  • Checked layers/visibility
  • Waited for the file to load
  • Tried changing camera/view direction

But the issue is that both Object and Imported panels are completely empty. However, the saved scene thumbnails on the left side still show my project/model preview.

It looks like the D5 file still has the scene thumbnails, but the actual model/object data is not loading or has gone missing.

Can you please help me recover this project? Is there any way to restore the imported model/assets from the 4.3GB file, or check if the file is corrupted?

I have attached screenshots showing the issue. Please let me know what files/logs you need from my side.

Thank you.
