Lost project - recovered but damaged

Hi everyone.

I would really appreciate your help I am kind of lost here..

In the last month i worked on a project and everything was good.

I came back to fix some things in my project to find that it is'nt in the recent projects in premiere and i can't seem to find the project file in it's original location or anywhere!

I opened a recovery program that some how found the original file. I recovered it but premiere give me an error the the project is damaged.

I am using premiere 2021. never had this issue before.

thanks!
