"Dropbox Unexpectedly Quit" error on two Windows 11 computers
The Windows 11 Dropbox app updated on Wednesday and now repeatedly crashes. Software version 219.45.4463. The problem is present on two W11 devices, both received the Dropbox update. Dropbox and Windows 11 has been reinstalled on one device. Both are company managed and had no issues with Dropbox prior to this update.
Error message: Dropbox Unexpectedly Quit
Your files are safe. Restart Dropbox to resume sync and other features.
I have gone through Event Viewer but don't see any crash logs related to Dropbox.

Check the number of devices you have Drobox installed on. The limit is 3 for the Basic plan and I checked my devices and had on about 12. Once I cleared those out and brought to only 2 devices, Dropbox stayed connected. Easy fix
AVG Support worked on my PC remotely today using "Support-LogMeInRescue" for about an hour, and were not able to solve it. While they were working through after checking "Blocked & Allowed Apps", which I had already checked, I noticed them checking "Exceptions" and adding the link to the Dropbox shortcut which did not work. They said they would need to do further work offline, would terminate the session and call back. While waiting for the call back I went back to the "Exceptions" menu and added "C:Program Files (x86)\Dropbox\*" to "files, folders...to exclude from all shields and scans" and Dropbox started. While there are obvious risks to adding exceptions like this, for the moment, this has solved the problem.
AVG Support have now escalated the issue and I am waiting for a further response.
At AVG online support suggestion I have uninstalled and re-installed AVG Security. The problem is still there.
I now have to turn off AVG and start Dropbox manually after every re-start, and then re-start AVG. This is apparently a known AVG fault
Since upgrading to Windows 11 I have been getting this error. I thought it might be because the Dropbox installation was 32 bit and Windows 11 is 64 bit so I removed the app, reinstalled 64 bit and the app would not finish installing. I then allowed Dropbox as an app on my security program (AVG) - manually - as my security program did not see it. It still would not install. I then turned off the security protection temporarily and it finished installing and signed in. Today on re-starting the error came up again. I turned off the protection and reinstalled without removing and the app works again, with the security protection back on?
Done, thanks, seems to work for now.
