I'm seeing the same thing and have the same question. anyone out there know?
Hey Dan. Not a great solution, but the only thing that worked for me was an uninstall, and re-install. I had some Tableau Engineers look at my setup and they determined that some files where corrupted with all my uninstalling and installing. We uninstalled, deleted all the Tableau folders, re-installed and rebuilt all my content. I didn't have a clean backup which is why I rebuilt the whole thing.
Ouch, not the best solution.
I’ve been considering a reinstall on a larger drive anyway, but I was anticipating creating a backup first that I can restore on the larger drive. While being something less than a true clean install/rebuild, perhaps it would help.
