Random? catastrophic error on working project.

Got this error upon attempting to load up my FPSSample project after having worked in it less than 12 hours beforehand. After pressing continue, I'm missing the FPSSample menu option at the top of the project and random assets seem to have loaded in incorrectly. I've attempted re-importing all assets multiple times to no avail. Is there any salvaging my work and project at this point?

 

I actually encountered this error myself while starting up the project on a forked repository after having worked on it locally. And yes after pressing continue there was no FPS Sample Editor, nor any other editor file.

I had my work saved as a package, so I was able to just reclone the project and import my package and everything's fine. It does take time to rebuild and whatnot but everything works and is there. I'd suggest trying that if it will let you export.

 

You have to load your scenes though the fpssample/windows/project tool.
