My project and all incrementally saved versions will not open. "The project appears to be damaged"

[BIRDHAUS]

The project appears to be damage and cannot be opened. This error popped up this morning.
Steps thus far: Updated Beta. (No luck)

Tried importing (No luck)
looked for the 2 files that premiere sometimes produces, they don't exist.
Is this a known issue or an isolated bug. I have never had an issue quite like this.

This is the same thing I experienced.

You may be able to recover your project file. 

Have a temporary work around I outlined here:
