"Dropbox cannot start / Dropbox ran into a connection issue" error (macOS Monterey)

[Davide_Saraceno]

Hi,

Dropbox app used to load at startup and work smoothly on my Mac but since a few weeks Dropbox can’t load at startup, giving the following error dialog: 

"Dropbox cannot start / Dropbox ran into a connection issue"

I click OK and get another error dialog: "Couldn't start Dropbox. This may be a temporary error. Please restart Dropbox. For more information, click the help button.” so I get the error log (see below) and click OK.

After these steps I’m always able to open Dropbox app from the Applications folder and everything works fine.

So, my issue is only at startup time, when some sort of "connection issue” happens.

Please be aware that I’ve already done an advanced re-install (twice!) and all the necessary Accessibility/Full Disk Access/Files and Folders settings are ok.

Could you help me?

Thanks,

Davide
