The file cannot be evicted.

Start with this of M1 or M2 Mac...

Start up a Mac with Apple silicon in safe mode

On your Mac, choose Apple menu  > Shut Down.

After your Mac shuts down, wait 10 seconds.

Press and hold the power button on your Mac until the startup options window appears showing available startup disks and Options.

Select a startup disk.

Press and hold the Shift key, click Continue in Safe Mode, then release the Shift key.

To leave safe mode, restart your Mac normally, without pressing and holding any keys during startup.

This has also happened to me after an awful new Dropbox update that doesn't seem compatible with OS Ventura 13. Huge problems with synching and now I get the error message: the file " name" cannot be evicted.

I get HUNDREDS at a time. It's annoying, and it's scary.

Here's what I get from support:

"Could you confirm if you have recently upgraded your Mac to the latest version (13)? If so, kindly note that, this is most likely the source of the inconsistencies you are seeing, rather than the latest stable version of the Dropbox desktop application. In fact, it is important to be running the latest version of the Dropbox desktop application at all times and it is not possible to revert to a previous version."
