Running Tableau Prep 2018.2.1 on Windows 10. Tableau Prep stopped working this morning and not sure why. When I try and start the program, I see the start-up screen but it never actually opens the program. It just hangs at that point. I have uninstalled, reinstalled, rebooted, deleted the Tableau Prep folder in "My Documents" folder and none of it makes a difference. I have tried starting it as Administrator and no difference. I have tried opening the software directly as well as double clicking on a flow and still the same issue. It has been working fine on my laptop until this morning. I do not think I changed anything on the machine.
I have copied the log files, zipped them, and attached them to this message. Any ideas are appreciated.
