Project file has disappeared Reolve 12.5

Hi,
I'm using Resolve 12.5. I created a new project yesterday and now it is not showing up in the project manager (regardless of which user I login as). And yet I can see some supporting files in a folder with the project name saved on the C drive in this location:
C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\Resolve Disk Database\Resolve Projects\Users\guest\Projects
I know I saved that project like a hundred times when I was working on it...
