Loading Visual Studio toast does not close

The Loading Visual Studio toast never closes after opening Visual Studio by double clicking on a C++ Class or Blueprint node.

I do not see this issue when I select File > Open Visual Studio 2017.

1. Open UE4Editor.exe
2. Open any Code project
3. Select Edit > Editor Preferences > Source Code
4. Set the Source Code Editor = Visual Studio 2017
5. Select Restart Now
6. Ensure that no instances of Visual Studio are running.
7. Enable Show C++ Classes in the Content Browser view options
8. Double click on one of the C++ Classes in the Content Browser

RESULT:
Visual Studio opens and the Loading Visual Studio toast never closes.
