Can you clarify for me if when you reinstalled, you first uninstall and installed again from scratch or did you simply download and install over the current software?
If it was the latter, would you mind uninstalling first and then downloading and installing again to see if that will do the trick? The issue could be due to a potential issue with executable files, since there is no specific error message I wouldn’t be able to say this for sure though.
Otherwise, if you’re still seeing the same behaviour or already did this previously, can you please try an advanced reinstall of the desktop app? The full steps to do so are outlined here in our Help Center article.
Unfortunately, I (mobo) signed in with a different email and can't delete the post to put it on properly.
Uninstalled the most recent windows updates, uninstalled and re-installed Drop Box client. I noticed that it works on a different user but not on that user. (The user that I tested was not a domain user.)
