"Critical Error saving project" - Project is gone missing

Dear Resolve Crew,
we were editing a project in Resolve Studio this day and suddenly - we were almost finished - a warning pops up: "Critical Error saving project" with the options to Export the project or Restore it. Unfortunately both options didn't work, resulting in critical errors. From then on, Resolve was completely frozen.

After restarting Resolve, the project is completely missing from the database. No matter what we do, it won't show up - although the project folder and the Project.db exists in the database folder. We have tried the following:

• Creating an empty project and pasting our project.db into the newly created project -> new project is also missing
• Created a new database and put the project in there
• Refreshed everything and restartet the computer a couple of times

Now, we are a bit clueless. We would loose the work of an entire day - Backup .drp from yesterday exists, but since then a lot has changed and we've put a lot of work into it.

Does anyone have an idea how to repair the Project.db? It's about 16 MB and if viewed in a text editor, the header seems to be more or less the same style as another working project, so it can't be totally shredded.

Any ideas?

Best from Hamburg

Did you have Project Backups enabled?

Odds of repairing a corrupt Project.db file are low, but if you want to provide a link to it, we can take a look.

Also, are you using the default Local Database, or a database on an external drive? We don't recommend putting databases on external removable drives. But if you do, it can't be ExFAT formatted or you'll get random failures.

Hello Dwaine,
thanks for your quick response. The project database is located on a local (C:) drive, but within a OneDrive folder so it get's synced to the cloud. Maybe this could have caused the problems?

Please find a link to the corrupted Project below:

Thank you very much for your help!

You absolutely should not have the database on a "synced" folder such as Dropbox or OneDrive.

The Project.db file is not recoverable.

If you enable Project Backups in Resolve Preferences - User - Project Save and Load - Save Settings, you'll have additional protection if something like this happens again. Make sure you select a valid Project backup location.

Hey Dwaine,
thank you for your reply! That will be the cause for the problems. We will set up an SQL database to prevent these kinds of problems in the future. Thank you for your help!

All the Best,
