Couldn't Start Dropbox - macOS Monterey

Hi there,

I have just updated to macOS Monterey and Dropbox won't start. Anyone else with the same issue?

Thanks

I'm having the same problem.  Error message simply states "Dropbox unexpectedly quit".

I was able so solve it by performing an advanced-reinstall. For it to work properly, I had to rename my remaining dropbox folder after uninstalling the app (I did it between steps 2.2 and 3). Once the installation was complete, a new folder was created and synched. I then deleted the old renamed folder. 

I received a new M1 MacBook Air yesterday. After I transferred my data from my 6-year old Intel MacBook, I was prompted to upgrade my new MacBook Air to Monterey. After the upgrade, it's running Monterey 12.01. During the installation I got a message that the Dropbox app wasn't supported, and indeed it was evidently automatically removed from the Applications folder. The Dropbox app was totally up to date before the transfer. What the heck happened?

I am having this issue. I cannot even get the icon to stay in my menu bar, so I cannot follow some of the troubleshooting tips mentioned on other threads. I am not an advanced user so do not know how to do a lot of the advanced steps that I see. Could somebody walk me through what I need to do to get this working, please?  Thanks,

Jon

Same issue. I've been running macOS 12.1 Beta version Beta (21C5021h) and Dropbox seamlessly until 11-4-2021. I have the error message as follows:

Thanx

Let me add some later info. I told Duck DuckGo to find me a Dropbox download site; it found yours and I downloaded the app installer. The installer ran without complaint and left the Dropbox app inside the Applications folder. It opened but would not sync. I adjusted permissions using info acquired here, but also found an "error" indicating I was required to upgrade if I wanted to sync among more than 3 devices. That puzzled me until I figured out that though I'd already wiped my old Intel MacBook, Dropbox thought it was still alive, so I now had four devices. Just a little poking around found a device list in Dropbox, where I could check (or uncheck)  a box and remove the old computer from the sync list, making Dropbox happy again. Whew. 

I followed these instructions to the letter by doing this:

Preferences > Security and Privacy > Accessibility, Full Disc Access, Files and Folders and made sure that all are set to Full disc access or all folders are selected. I have rebooted my computer after making those changes.

No effect. Still get same issue with the pop-up error with link to error code.
