This has been reported in 1.0.18.6 and 2.0.0.0. It's likely due to 7a88701

Currently, our Beta version crashes the Team Explorer pane when a user logs in, perform no action in Visual Studio, closes app and relaunches app.

Steps to Reproduce

• Launch Microsoft Visual Studio and connect to GitHub from the Team Explorer
• Sign in with valid credentials.
• No project added prior or cloned.
• Close Visual Studio app without signing out.
• Relaunch Visual Studio

Expected result - Visual Studio should launch with user's GitHub account already connected in Team Explorer.
Actual result - Visual Studio launches with error messages in Team Explorer.

GitHub Extension 2.0 Beta Version.
OS - Windows 10
Microsoft Visual Studio Enterprise 2015
Version 14.0.25424.00

Screenshot is as seen above.
