Launcher comes up but fails to refresh access token and closes to desktop

When I click the menu link to launch the game, the launch screen comes up and seems to hang, then closes. I've uploaded a video of this to youtube: https://youtu.be/8JCYDvuBCF0

The launcher_log.txt file is attached and seems to indicate that the launcher cannot access the refresh token. This started on or around 12/18/2018 and has been happening ever since. I kept hoping another release would come out that would fix it, but that hasn't happened yet.

I have also attached a text file with the error that is logged to the event viewer.

Please let me know if there's anything I can check or provide to you to help diagnose this bug.
