Also having the exact same issue with my 2015 Macbook Pro. Dropbox was working fine until the Monterey 12.0.1 install. Now I always get the error message that Dropbox can't start when I reboot the computer. This really needs to get fixed by Dropbox asap if they want to maintain credibility in the Mac user community

[drmajorbob]

Monterey caused the problem. Maybe Apple should get your complaint.

Dropbox is big enough of a Silicon Valley company to have been able to plan this move, just like any other OS upgrade... it's up to Dropbox teams to sync with Apple dev policies, not the other way around!

[andreabonato]

This is a step by step sequences....!
1) by Activity Monitor (you find it in Launchpad-Others-Activity Monitor) search and select all Dropbox items (especially Dropbox Finder Extension) and stop by the :cross_mark_button: or X bottom on the top of the app;
2) by Force Quit (in the System Menu Screenshot 2021-10-29 at 09.50.19.png) refresh or relaunch Finder;
3) in System Preference-Security and Privacy-Full Disk Access (after clicking lock to make change in the bottom left corner), enable Dropbox.App.
4) I think is better to restart computer after that.
I insert more usefull instruction.
I hope you solve your problems!
Bye.

"full disk access??? in your instructions? Sorry i don't see that anywhere

[alakija]

I tried everything on this string of suggestions. nothing worked. My solution was to take everything I had in Dropbox and put it in iCloud. Maybe this is what Apple wanted. 

If I cannot open or sync Dropbox on my main computer, it is not useful to me anymore.

Sorry, I loved Dropbox while it worked.

@andreabonato 

fake news, we tried this already, it's hit or miss but for most people won't fix it permanently.

[Kit68]

Just tried it and it helped me too!  Didn't need to force quit finder, but took the other steps (force quitting dropbox in utilities, and then accessing and enabling Dropbox in privacy/securing setting.  Thank you, Andrea!  I was tearing my hair out! 

[BSBecker]

Thank you!  This worked for me!!

[BSBecker]

andreabonato  Nix that thank you.   It worked for a moment, but its obvious it is not syncing.  I just uploaded something from my phone and they are not talking to each other at all.

Ughh.. time to move everything to google drive or the cloud.
