To solve the problem, I close all Dropbox items by searching "dropbox" in the Utility Monitor.

Than I refresh Finder by Force Exit in the system menu.

Finally, in System Preference-Safety and Privacy-Complete Access to Disk, I've able Dropbox App.

All now is working!

Bye.

Hey guys, thanks for the comments here!

@Jhirstz, did you get a chance to try what @andreabonato suggested?

[AMCPA]

After trying everything several times, including terminal commands, andreabonato solved my problem! Thank you so much!

[Hannah]

That's great @AMCPA! I'm happy to see that the issue was resolved.

Let us know if you ever need anything else!

I had luck uninstalling Dropbox (moving to trash, emptying trash) and then getting rid of the Dropbox application settings:

In Terminal:

mv ~/Library/Application\ Support/Dropbox ~/Desktop/DropboxOldSettings

Then reinstall Dropbox.

Oh, I also noticed that the permissions for the disk were bad before that.  In "Get Info" for the Dropbox folder, I unlocked the permissions (lock in bottom right corner), and chose "Read & Write" for "everyone".

[drmajorbob]

That worked for me.

Thanks for that process. It worked for me also. 

Do you happen to know if there are any security concerns with giving Dropbox full disk access?

[andreabonato]

This in what read about risks of Full Disk Access:

"Full Disk Access is a security feature, introduced in macOS Mojave, that requires applications to be given full permission to access user-protected files. If not enabled, some data on the Mac will not be accessible. In previous macOS versions, this permission was automatically given during installation.

Accessibility allows an app to control and listen to the system outside of its own container. This is often used for apps that extend system functionality or run processes in the background, such as productivity apps.

It’s also not something you should be afraid of, as it is just marking an app as trusted so that it can access your data. You’ll still only want to enable apps that have a good reason to be scanning your whole drive, but in reality, there’s not too much locked down behind the “Full Disk Access” permission.

However, this doesn’t give the application root access, which would give it the ability to delete or modify the system files macOS uses to run. You’ll have to put in your password manually if an application wants root access."

I think that Dropbox is a reliable app.

Thanks!

Hi everybody,

Since I installed Monterey Mac version, my application Dropbox doesn't work.

I have this message : 

"Cannot start Dropbox. A permission error is usually the root cause of this problem. An error could also occur if your user folder is stored on a network share."

Is there a solution pour this ? 

Thank you
