Hi Will,
- How has this thread existed on the adobe website for 20+ days without anyone from Adobe commenting?

Very sorry for the frustration. Unfortunately, we cannot respond to every post here, and I apologize for that. We in community support try our best, but this is largely a user to user style forum. If you want a guaranteed response from Adobe support, with a corresponding case number, please contact us any time here: Contact Customer Care.
I'm very, very sorry if you were not aware of this option.
Creating a new user account on Windows 10 worked, I created it and started Premiere CC2019 and it worked right away. So it's a user account issue with files that are getting installed in user accounts. This is beyond ridiculous....
Thank you so much for sharing your workaround. In any case, when you have to solve this issue by creating a new account, that's quite annoying. These issues are kind of rare, but recently I've seen it related to installations of AVG antivirus. Is it installed? If so, my advice is to uninstall it, as it is known to cause problems with importerquicktime.prm.
If you do not have this antivirus software, check the antivirus software you do have installed for potential issues.
If this still does not solve your problem, another user had success using this method:
Finally, contact support if you need additional assistance and get a case number filed with our video queue.
Thanks,
