Describe the bug
Visual Studio crashes sometimes when opening Team Explorer after just starting up Visual Studio.
My fellow team mates have the same behavior on their machines from time to time. Could it be performance related? When repeating the steps from the reproduction it will not crash after a few retries.

Eventlog shows .NET Runtime error:

Application: devenv.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
