Unable to see anything after downloading zip file in post processing stage

I was working on this ring magnet project for a long time and it shows nothing after I downloaded the zip file in Windows. I was trying to see the data at different points on Paraview. Whatever electrostatics model I try to download it shows nothing in the .zip file even though I am able to post-process my runs in SimScale. PFA the screenshot.

Link to my project: SimScale Login and this project is private.

Also I am unable to make it from private to public. Please do it urgent.

Can you approach us on chat support?
We will then look into your private project settings
