Project.db not being detected by Project Manager

Recently, a project I've been working on for about a month has stopped appearing in the Project Manager of Davinci Resolve. I do not have any Backup .drp files of it (I'm starting to learn how important it is to make those often), but I do still have the Project.db file, which I found here:
C:\Users\Luke\AppData\Roaming\Blackmagic Design\DaVinci Resolve\Support\Resolve Disk Database\Resolve Projects\Users\guest\Projects
After researching for a bit, it seems likely that the Project.db file is corrupted somehow, but also that there is also hope in fixing it, if someone were to dig around in the file.
Is there anyone here able and willing to do that? Or could I be pointed in the right direction to someone who can or how I could do it myself?
Or maybe even some other solutions that slipped past me to try?
