Partially overwritten aup3

So I was running a shredder program, there happened to be a shortcut to my project in the directory I was shredding - I stopped it just as it started erasing my project but unfortunately the project has been corrupted. It's 1GB and most of it should be intact just a few seconds in I stopped it.

Attempting to recover or extract files from it gives me the error: "file is not a database".

Any suggestions? I do know that the part which is overwritten is un recoverable, just whatever clips are left is what I'm looking for.
Help would be appreciated.

The report concerns a partially overwritten .aup3 project and the error “file is not a database.” It names no repository file, test, or entry point; the scope and a verifiable definition of done for recovering intact clips are not specified.
