Thank you for getting back to me. The error message I receive is at the top of this stream. FYI I have deleted and re-downloaded the installer numerous times and always get the same result. Also shut down and restarted the computer after deleting the installed app and the installer. None of that worked. I am running Mac OS BigSur version 11.4.

Keel me posted with your progress!It worked! I must tell you, the Terminal thing is not easy to figure out but after a couple tries, I got it.
The advanced reinstall works (as does re-initializing the drive, reinstalling the macOS, and then restoring files/applications/etc from a Time Machine backup previous to the appearance of the problem). However, the Cannot Start Dropbox error keeps coming back—in some cases after any restart, or after sleep (note: my SSD is set to never sleep), or—as in this last reinstall of Dropbox—upon the first attempt to start Dropbox at the end of the install process. I have made sure the Dropbox app is allowed incoming traffic through the firewall, I have excluded the Dropbox app from being scanned by Bitdefender anti-virus.
Dropbox has become unusable. This is a REAL problem, as I use it to coordinate with colleagues (other consultants) for work. If Dropbox doesn't fix this new (only began in the last two weeks - no changes in my software/OS during that time) problem soon, I will have to abandon it for some other cloud service. I like Dropbox and have never had problems like this before.
