I was able to fix this -- you have to uninstall (reboot) and then re-install dropbox. That re-installed all the permission stuff and got it working. Sadly there is no 'repair' option and I just went right for uninstall/reinstall.

The problem is related to credentials. Dropbox app in Windows uses onedrive to create a virtual drive. You want to be sure that you are logged into onedrive with credentials that grant you access to the windows local drives or Adobe apps you expect to use.
Best to uninstall and reinstall the dropbox app, and it should reset credentials. Worked for me.
