Cannot Open VS Project From AOT (One or more projects in the solution were not loaded correctly.Please see the Output Window for details.)

When I edit the VS Project from AOT, the VS show an error : "One or more projects in the solution were not loaded correctly. Please see the Output Window for details."

I am not sure why this happened. But I have a temporary solution can open the VS Project before you fix this error. 

First, see the output window for the details. There will tell you where your project exist.

Then open the File Explorer, locate that path.

Double click the file .sln. Now you can open your VS Project and design your report.
