"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.

Thanks for letting us know about this, @jacob m.

Can you please check this article that has some troubleshooting steps for this error and let us know if it helps?

Thanks.

I've run through all those steps with our IT team and/or it was already working previously.

The latest Beta Build 220.3.3984 also crashes

Hannah

Thanks for the update, Jacob.

Can you also try these advanced reinstall steps, to see if they help?

jacob m

No change. I was able to complete steps 1-4 and 11, but RegEdit did not have any of the dropbox folders and they were missing from file explorer in steps 8 and 10.

The previous stable release 218.4.4348 also crashes. I was hoping since that worked before it would work again but it did not.

Hi @jacob m, in order to look into this matter in more detail, I'd recommend contacting the support team directly for them to investigate further.

This problem has been going on for a year or more now, no fix from Dropbox. Every time I paste or drag files into any Dropbox app folder File Explorer freezes. When I crash and restart File Explorer the files have always been successfully pasted. Dropbox says I am using 560MB of 13.5GB capacity on my free level, so this is not a capacity issue. Windows 11 Pro v 10.0.26100, Dropbox v 221.3.5302 Dropbox needs to pay attention and fix this.

Hi @Bulldog87, could you try reinstalling the Dropbox desktop application, without uninstalling it first, by using this link?

Bulldog87

Done, thanks, seems to work for now.

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?

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

Buzon

At AVG online support suggestion I have uninstalled and re-installed AVG Security. The problem is still there.

Buzon

AVG Support have now escalated the issue and I am waiting for a further response.

Hey @Buzon!

Thanks for the heads up regarding the case. I'll be waiting for more info about this.

If you need something else, please let me know and I will be more than happy to help every step of the way.

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.

Walter

We're happy to hear it's sorted now and thanks for the update too @Buzon

Let us know if anything else comes up!

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
