Spotlight Search Doesn't Link to Files in Dropbox in macOS 13 Ventura

That’s the same problem I had. I solved it by doing a complete clean install of dropbox. You may not need to do all of this, but to be safe, in Dropbox settings Selective Sync uncheck all of your folders and wait for them to be removed from your Mac. Once that’s done, unlink your Mac from Dropbox preferences. You should see the Dropbox getting started screen. Quit Dropbox and move the app to the Trash. Remove all dropbox files from ~/Library being careful to look at the path name. Only remove things that are within a Dropbox parent folder. Look in library application support, and library preferences. Empty the Trash. Restart your Mac. Reinstall Dropbox from dropbox.com. Once reinstalled, to make things faster sync only one small folder and wait for the prompt that new Dropbox for macOS 12 is available. You should see the message within a few minutes of reinstalling Dropbox. Allow it to upgrade and migrate your files to the new location. Once that’s done you can then sync all your folders. Let your Mac index itself and the problem should be solved.
