Tray Icon stucks on loading when opening in Windows 10

Hi guys,

following problem:
- after reboot of my system, Keybase do start automatically with the system start, but it does not login.
- When opening Keybase via the tray icon in the task bar, the main screen stucks at "Loading.

Configuration:
- Windows 10 Professional 64 bit
- Keybase GUI Version: 1.0.36-20171121163724+f68b10e

I tried following things:
- uninstall / install keybase
- deleting it from autostart
- starting Windows with and without network connection
- installed it with and without administrator previliges.

Any Suggestions?
Thank you!

The report concerns the Windows tray icon, automatic startup, login, and the main screen remaining at “Loading”; no source file or test is named. Start by reproducing the behavior after reboot with and without network access, then trace the tray-icon launch and startup/login entry points. Done means the main screen loads and the client can log in after automatic startup.
