As of today 2019/04/04 Dropbox won't open properly unless I ran the app as an admin.
Noyhing changed on my Windows 10 PC, same hardware, same Windows, same folder location.
I get a popup error, this one below:

And the generated txt file says this:

Now if I change the shortcut or exe permissions and set them to Run as admin, it works just fine. Is there anything I should do to make it work like before?
