Reverting a revert action

I did a revert to my project because I needed to go back a version but it sent me all the way back to the beginning of the project, with only one track. I need to revert the revert but nothing is working and I need my project back

In an emergency state of this kind, when everything goes wrong, have you tried to quit Cubase WITHOUT saving the project reduced to its beginning ? If so, you should be able to retrieve your project as it was before the ‘Revert’ session.

Beside this, and looking in your project folder, no previous .cpr file or .bak one that could help ?
