Could you please try an advanced reinstall with admin privileges and let me know how it goes?
While at it, please make sure that there's no antivirus or firewall that might be causing issues.
Keel me posted with your progress!

Out of the blue, with no changes to my system or environment, the startup failures have returned. This is extremely frustrating!

Hey Tim T. and MikeB2, thanks for reaching out.
Can you try the steps here for a more advanced reinstall of the Dropbox application, to see if that helps?
Let me know how it goes.

Same result. After install and login, when I hit the Next button (to open the app), I get the same error. I have never moved my Dropbox folder. I ran the app fine for months after migrating to my new Mac. This error just started a few weeks ago. Should I have disabled the admin privileges of the user before running the installer? I had them on to run the suggested Terminal commands. I left admin privileges on when installing. I am at a loss, and this is causing major headaches for two work projects. I have to download files from the web version of Dropbox, modify them and them upload them back. There's lots of room for problems. My local Dropbox no longer reflects the online version (not sync'd, because I cannot get Dropbox app to start. Here's the full log:

So, it turns out my anti-ransomware (folder/file protection) software was causing issues. It may have started to block Dropbox after an update or something(?) I removed then restored authorization for Dropbox to access my protected folders (including the Dropbox folder), and it seems to be working again.
- Tim T.4 years agoExplorer | Level 3
I tried this (removing then reauthorizing the anti-ransomware protection). It didn't work for me (at least immediately). Did you need to do the advanced install again (e.g., remove authorization, then do advanced install, then re-authorize protection)?
- MikeB24 years agoExplorer | Level 3
I ran the advanced reinstall, it didn't work. Then I updated the protection software, and Dropbox started working immediately...
