Please help me - urgent error

Hi Guys

I was working on Premiere Pro 2020 14.0 on my 2017 macbook macOS Catalina 10.15.3, Radeon Pro 560 4GB gpu

Everything was fine, i saved and closed premiere like I always do. 

When i tried to open it today i got the following error: Premiere Pro: The project could not be loaded, it may be damaged or contain outdated elements"

What I have tried: (did not work)

1. uninstall and re-install of Adobe creative cloud, all apps and cleaned with adobe cc cleaner.

2. tried the auto-saves there are over 15 and non of them work

3. tried creating new project and importing the damaged project as entire project and selected sequence.

4. Updated my Premiere Pro to 14.0.1

5. Downgrading the project file to a older version of pp 

6. I signed out of creative cloud app and opening the project same error

7. I tried resetting the media cache and preferences, and opening pp while holding option key. 

8. Tried opening the project on another mac and another windows system same error

9. I tried Renaming the “Creative Cloud Libraries” folder 

10. Created a new account on my Mac, logged into that and openned the project in premiere - didnt work

11. Copying the whole project to another drive. 

This project was a lot of work on a 24minute tv episode. I really need to get it back. I have a folder full of auto-saves that doesnt open. What else can I do?

Please help- i have a deadline due
